Type 1 : Speed of boat in still water and speed of stream are given separately. Correct answer : b Hint: In downstream, water stream increases the speed of boat as they both are along the same directions.

Hence, both the speeds are added. Find a speed of stream b speed of boat in still water. Find the distance covered by the boat between two points.

Next Page �. If there's no mention of stream speed in the question, assume it to be the speed of boat in still iwndows. So, water stream increases the speed of boat.

Hence, boqt are added while going downstream. So, water stream the speed of the boat upstream windows 10 the speed of boat due to opposite flow. Hence, speeds are subtracted while going upstream. If you just remember this concept, you won't need to remember and recall the above formula while solving the problems.

Halving this would give you the speed of the current. Once you know how to deal with these 4 types of problems, the chapter should be an easy one for you.

Yet there were still floods and other problems. By , so many vessels were unfit for navigation that the company required boats to undergo annual inspections and registration. In July , the crew of the Lezan Ragan stayed afloat while loading in Cumberland only by her crew's pumping.

She hit some abutments of the locks near Great Falls, and finally sank at the opening Lock 15 at the head of Widewater. For a brief period in the s and s, the company attempted to prevent boating on Sundays.

But boatmen broke padlocks on the lock gates and turned to violence when confronted. The company gave up trying to enforce the rule. The trip from Cumberland to Georgetown generally took about seven days. Dent Shupp made it from Cumberland to Williamsport in 35 hours with tons of coal. Over the next decade, and particularly after , boats on the canal shifted from independent operators to company-owned craft.

Boats with colorful names Bertha M. Young or Lezen Ragan gave way to numbered craft "Canal Towage Company" with a number run by a schedule. Tolls were charged for cargo on the canal. In , for instance, the toll rates on the Canal were set as follows: [67]. Some boatmen would try to ship in the boats extra cargo not listed on the waybills to avoid tolls. In , for instance, one boat got from Georgetown to Harpers Ferry with hidden sacks of salt before the company found out.

The items transported on the canal varied. In , for instance, before the canal's completion, the shipments were as follows: [69]. After , the canal principally transported coal, and sometimes West Virginia limestone, wood, lumber, sand, and flour. Statistics were only kept for coal. Some of the coal had to be shoveled by hand into the spaces beneath the cabins. During the loading process, nobody would be on the boat due to the dust, and mules were kept off, in case the boat sank from being loaded.

Despite closing windows, dust usually entered the cabins. After loading, the ridge poles would be put, then the hatches over the ridge poles and openings. The crew would scrub down the boat using water from the canal to remove the dust, and the boat would be poled to the other side of the basin, where it would be hitched to the mules.

Boatmen came down to lock 5, called "Willard's lock" or "Waybill Lock", whereupon the locktender would sign the waybill, and report it to the office. If they did not get orders at that lock, they waited near the aqueduct bridge in Georgetown, until orders came through. A tugboat on the river would pull the boats to other points, e. Navy Yard, Indianhead, Alexandria. Coal was also unloaded onto ocean sailing vessels bound for Massachusetts which brought ice, and returned with coal , a 4 masted vessel holding about 20 boatloads of coal.

In the last few years, the tonnage and tolls for coal were as follows [70]. One of the more unusual loads was a circus with about 9 people with their equipment, which included a black bear. They were transported from Oldtown, Maryland to Harpers Ferry. The black bear got loose on the journey, and the boatman told them, "You tie that thing good or you're never going to get to Harpers Ferry, for I'm The Speed Of The Boat Upstream Touch going to leave the boat.

Other loads included furniture often second hand , pianos, a parlor suites, watermelons, fish such as shad and herring , as well as transporting items such as flour or molasses to sell to lockkeepers, [74] as some of the lockkeepers in remote areas needed the boats to bring their supplies. Some would pole across the river at Dam No. Other loads, often carried upstream, included empty barrels in a boat, taken to Shepherdstown to load cement, lumber, fertilizer, and general merchandise for stores along the canal, as well as oysters in barrels, complete materials to build a house, ear corn, and even extra mules.

The company levied fines for infractions, such as traveling without a waybill or destruction of canal property such as lock gates or canal masonry. For instance: [77]. The last known boat to carry coal was Pat Boyer's Boat 5, which returned to Cumberland on November 27, The only boats recorded to operate in were five boats that carried sand from Georgetown to Williamsport to construct a power plant.

The flood of caused major damage to the canal. Most of the railroad and canal bridges near Hancock were destroyed, a breach opened in Dam No. Although the railroad did some maintenance, ostensibly so that the canal could quickly be restored to operation, mainly the Georgetown level Dam No. Unfortunately, some communities such as Glen Echo and Cumberland already used the canal to dump sewage, and G. Nicholson called the canal a "public nuisance" due to the sewage and being a breeding ground for mosquitoes [80].

After the flood damage of , the railroad only fixed the part of the canal serving Georgetown, since they sold water to the mills therein, leaving the rest of the canal in disrepair. In �, there was some talk of restoring and reopening the canal from Cumberland to Williamsport, but with the onset of the Great Depression, the plans were never realized [81] In April after some freshet damage, the railroad repaired a break in the towpath, so that they could continue to flush out mosquitoes as demanded by the Maryland board of health.

The boatmen, now unemployed, went to work for railroads, quarries, farms, and some retired. At that date, the only other canal using mules, was the Lehigh Canal , which was soon to close in Some of the lockkeepers stayed on, and there were a few canal superintendents were listed for the now disused canal.

This winter flood in March caused even more damage to the abandoned canal, still recovering from the damage caused by the extreme floods just over a decade prior. This flood, caused by the thawing of earlier ice, combined with the flow of heavy rains, led to the highest water mark the Potomac River had ever had thus far, destroying lockhouses, levels, and other structures.

There were some efforts at restoration, mainly to the Georgetown level so that the factories could have their water supply. The dimensions of the canal vary quite a bit. Below Lock 5, the width is 80 feet wide and 6 feet deep [87] Above Lock 5 to Harper's Ferry it is 60 feet wide and 6 feet deep, and above Harper's Ferry, 50 feet wide. Seven guard locks, often called inlet locks numbered 1 through 8 were built to allow water and sometimes boats particularly at Big Slackwater and Little Slackwater to enter.

Dam 7 and Guard Lock 7 were proposed near mile at the South Branch of the Potomac but never built. Later, in , a new steam pump was put near mile Three additional river locks were built, to allow boats to enter the canal at the river, as demanded by the Virginia legislature for buying canal stock. The lock was eventually converted into a waste weir. The Shenandoah river about feet below Lock 33 lock let boats cross to Harpers Ferry with the mules walking on the railroad bridge, up the Shenandoah river, to the old Potomac Canal Bypass on the Shenandoah river by Virginius island.

The railroad refused to let mules walk on the bridge, and from lack of business, the lock was abandoned. Stones from that lock were used for other purposes. At night, locktenders were required to remove the cranks and handles from all paddle valves to prevent unauthorized use.

Despite Mercer not wanting any composite locks, due to measures to economize on the last 50 miles of construction, and the scarcity of good building stone, Locks 58�71 were constructed as composite locks, whereby the lock masonry is built of rubble and inferior undressed stone. Since that makes a rough surface which damages the boats, the locks were originally lined with wood to protect the boats.

This wood sheathing had to be replaced. The stretch of canal between locks is called a level. Canalers called these levels by their lengths; for instance, the longest level was the 14 mile level, which was about 14 miles long, and ran from Lock 50 at 4 locks to Lock 51 in Hancock.

Some levels had additional nicknames since some had similar lengths , e. Levels less than a mile between locks were called short levels. There were three streams used as feeders: Rocky Run feeder section 9, around 7 Locks , Great Falls feeder section 18 and the Tuscarora feeder section There was a contemplated feeder at the Monocacy not built.

Inlet Lock No. The remains of the Tuscarora feeder can still be seen, but it was made redundant by Dam No. Despite Charles F. Mercer, two slackwaters were used for navigation: Big Slackwater at Dam No. The boats had to navigate despite winds, currents, and debris in the channel. In February , the board of directors discussed using steam power in the slackwater for the boats, but instead decided The Speed Of The Boat Upstream 730 on a permanent towpath.

Little Slackwater was a tricky place to navigate. Not only did it have a lot of hairpin turns, but also just before Guard Lock No. If the current was fast in the river it could go as fast as the boat, rendering the tiller useless, and thus, a boat could be almost impossible to steer.

Keim, their two daughters, and Harry Newkirk aboard. One daughter drowned, another suffered a broken leg, and the captain died later of injuries. The rest including the mules aboard survived. Boatmen reported that it was easier to navigate in the slackwaters than the aqueducts, since there was room for the water to move around the boat. Places like aqueducts, where there was little room for the water to move, were difficult for the mules to pull the boat through.

To regulate the level of water in the canal prism, waste weirs, informal overflows, and spillways were used. Waste weirs removed the surges of water from storms or excess when a lock was emptied. If one had to empty the whole level for winter, repairs, or emergencies, waste weirs often had paddle valves similar to those found in locks at the bottom which could be opened to let the water out. Waste weirs come in several styles.

Originally they were made of concrete masonry with boards on top making a bridge with mules to pass over. A possible example of an old-style waste weir abandoned is at Most of these old waste weirs were replaced with concrete structures in Spillways are made of concrete, and can be on either side, but if on the towpath side, have a bridge so people and mules can cross without getting the feet wet.

High water simply flows over the spillway and out of the canal. The longest spillway, near Chain Bridge, is feet long, was made in but has been worked on since. The spillway and waste weir at Big Pool was built in the s []. An informal overflow or mule drink was a dip in the towpath allowing water to flow over, similar to a spillway, but without the bridge or the concrete construction hence, were more informal.

The canalers called these "mule drinks". Historically the towpath dropped two feet to form this overflow. Hahn states that clues to finding these overflows include: a gully without a culvert, a sudden lowering of the towpath, or the signs of riprap on the towpath or the gully itself.

One of the most impressive engineering features of the canal is the Paw Paw Tunnel, which runs for 3, feet m under a mountain. The tunnel took almost twelve years to build; in the end, the tunnel was only wide enough for single lane traffic.

The company official threw green cornstalks onto a roaring fire at the upwind portion of the tunnel, smoking the offenders out. Engineer William Rich Hutton was instrumental in getting the inclined plane built. They then planned to make an inclined plane, much like the Morris Canal. It originally used a turbine to power it like the Morris Canal but was later switched to use steam power.

It was divided into sections with three switches, placed respectively at Dam No. Lock To carry small streams under the canal, culverts, [] usually of masonry, were built. For instance, culvert 30 was built in to carry Muddy Branch under the canal. Eleven aqueducts carried the canal over rivers and large streams that were too large to run through a culvert.

The canal hired level walkers to walk the level with a shovel, looking for leaks, and repairing them. Large leaks were reported to the division superintendent, who would send out a crew with a repair scow. Boatmen said that crabs caused leaks, as did muskrats.

The company gave a 25 cent bounty on each muskrat. That would permit boats with cargo up to tons. The following classifications of boats originally defined for the canal were as follows: [].

Rafts [94] were, from time to time, on the canal, as well as launches and canoes. By no doubt due to complaints about drifting rafts the company put rates unfavorably against rafts. Classifications were to change. In , after the opening of the canal to Cumberland, the company adopted new classes of boats: A, B, C, D, E, and F, depending on dimensions and tonnage as follows: [].

Later years of Canal trade showed a predominance of coal carrying boats. In , the register lists boats owned by coal companies, and of the other boats, 8 were listed as grain carrying, 1 brick, and 1 limestone carrying boat, with the other 91 being general. During the declining years, freight boats were generally made in Cumberland.

There were holes covered, when not in use that one could put a pump in to pump out the bilge. In , the Canal Company announced its intention to double the lengths of the locks to allow double boats to pass through the canal, i.

The Maryland Coal Company experimented with such boats, but the floods in the late s destroyed these dreams. Locks 25�32 were extended as such, as well as others, for a total of 14 extended locks on the canal. Boats were to keep to the right. Certain craft had The Speed Of The Boat Upstream 720p preference over others: "boats had the right of way over rafts, descending boats over ascending craft, packets over freight boats at all times, and packets carrying the mail over all others", [] and later, repair boats actively involved in repair had preference over everybody else.

The towline of the one boat would be unhitched so the lines would not tangle, but sometimes they did. There is one report of a towline snagging on the other boat, and the boatman running the boat into the towpath so as not to drag the other mules into the canal.

It was forbidden to moor boats, rafts, or anything on the towpath side of the canal which would, of course, impede any traffic at night. Due to problems, on April 1, , the company printed a page booklet with new traffic regulations on the canal, detailing every aspect of operation, as well as fines for violations, and were printed in great numbers and distributed to boatmen and company officials.

The typical boating season ran from April until late November or December when the canal froze over. Boats carried oakum and chisels to patch leaks. The boat would settle on raised beams at lock 35, they were made of concrete , as the drydock was drained, and the men could make the necessary repairs, [] using tin and tar.

The company made provisions for drydocks to help the situation. Icebreakers were used on the canal, for instance, at the end of the boating season when winter froze the canal, so that the last group of boats could go home. The icebreaker was typically a company scow filled with pig iron. Mules would pull the boat onto the ice, and the weight would break the ice.

Icebreaker boats were used to keep the channel free of ice, so that the military could move supplies. Most boats were drawn by mules. Mules lasted about 15 years. Mules were often changed at locks, over gangplanks. Some boatmen would change teams by making the mules swim to the shore to change teams, leading to mules drowning as a result.

Getting a fully loaded boat moving was not easy for the mules, and overdriving them, especially at the basin in Cumberland where there was no water current to help them move the boat, was common, resulting in many spavined mules. Within 25 feet, the boat would be moving. Mules were shod every other trip in Cumberland, although sometimes they had to be shod every trip.

Dogs were useful to a boat captain on the canal to drive mules [] and also to swim to take the towline to hitch the mules. Horses were occasionally used to pull boats, but they did not last as long as mules. There were occasionally steam boats, one being authorized in [] In , the N S Denny company operated some steam driven tugboats on the Canal.

The boatmen usually with their families were a rough independent lot, forming a class within themselves, and intermarrying within their own group. They frequently fought amongst each other for any reason, be it racial slurs real or perceived , precedence at a lock, or for exercise.

They fought with lockkeepers over company rules, or even with the company for changes in toll rates. During winter when the boats were tied up, they often lived in their own communities away from others. On April 2, , Daniel Van Slyke reported: it is with great difficulty we have been able to preserve order among the boatmen, who in striving to push forward for a preference in passing the several locks are sometimes dis-posed to injure each other's boats as a means of carrying their point.

An unfortunate in-stance of this kind happened on Wednesday last at the locks on the 9th section. A strongly Speed Of The Boat Upstream 12 constructed boat ran her bow against a gondola loaded with flour, and so much injured her as to render it necessary to transship the load. But no damage was done to the cargo.

He refused to pay the fine. Recklessness among the boatmen was common. Many accidents were due to excessive speed. Aqueduct 3 Catoctin had a sharp bend at the upstream end, had been the site of a number of collisions from boatmen going too fast. In July , a freight boat collided with a packet boat which sank. One of the most frequent problems was careless boatmen in their rush to lock through, hitting lock gates.

Many of the men, particularly boat captains, said they knew nothing else [except boating]. One woman said, "The children are brought up on the boat and don't know nothin' else, and that is the only reason they take up 'boating'. Boys work for their fathers until they are big enough to get a boat of their own, and it's always easy to get a boat.

Fifteen hours a day was the minimum, 18 hours were the most frequently reported, according to the U. Department of Labor. Boatman said, "It never rains, snows, or blows for a boatman, and a boatman never has no Sundays. The boating season ran from approximately March until December, with the canal drained during winter months to prevent damage from ice [] and also for repairs.

Women attended to household chores, steered boats, and gave birth on the boats, although if possible, a midwife would be secured if they were near a town. After birth, the journey would resume, with the man handling the chores including cooking. Often if the husband died, the widow would continue managing and operating the boat. The U. Department of Labor stated that only the limitations of physical strength prevented the children from performing all operations connected with handling boats.

Children generally did the mule driving, except perhaps at night when the captain might do so. In wet weather, the towpath was muddy and slippery and shoes wore out quickly. One man thought himself to be a good father because he provided his boys with rubber boots. One boatman said, "A boat is a poor place for little children, for all they can do is go in and out of the cabin.

For boat families, there was very little medical care. One father stated, "We never need a doctor. We just stay sick until we get well. Canned food was sometimes brought. Bean soup, made with beans, ham hocks , and an onion, was common. Other items included corn bread, eggs and bacon, ham, potatoes, and other vegetables. A reported canal custom was the first few rows of corn from farms along the canal could be used by the boatmen.

Berries along the towpath were also picked. Molasses also was common. Bread and many groceries could be bought along the canal. Muskrats were sometimes eaten, as well as chickens and ducks either bought or even stolen along the way. Rabbits were snared. Crew members sometimes had a shotgun to shoot rabbits, groundhogs, or other game. Turtles were eaten as well as eels that the locktenders caught in eel pots in the rivers or the bypass flumes.

Fish included sunfish, catfish, bigmouth bass, and black bass. Cabins were 10 feet by 12 feet, and housed two bunks, each 36 inches wide, supposedly for one person, but often occupied by two.

While most cabin floors were bare, in one survey, 14 had linoleum covering.
