as the president of companies. The original engineering concept developed by the Society as well as the navigation company's charter had been to build a canal up to the Schuylkill Valley to Norristown, improving the Schuylkill river from there to Reading; while from Reading a canal was to extend to the Susquehanna, via Lebanon. This would have required a four-mile summit crossing between Tulpehocken and the Quitipahilla with an artificial waterway connecting two separate river valleys; namely the Susquehanna and the Schuylkill watersheds. Its successful completion would have made the middle reach, the first summit-level canal in the United States. The term refers to a canal that rises then falls, as opposed to a lateral canal, which has a continuous fall only. In this case, the proposed canal at 80 miles in length would rise 192 feet over 42 miles from the west at the Susquehanna river to the summit and then fall 311 feet over 34 miles to the Schuylkill river to the east. It was to be the "golden link" between Philadelphia and the vast interior of Pennsylvania and beyond.Breck, Samuel. Sketch of the Internal Improvements Already Made by Pennsylvania: With Observations Upon Her Physical and Fiscal Means for Their Extension; Particularly as They Have Reference to the Future Growth and Prosperity of Philadelphia. M. Thomas, 1818. This proposed summit crossing offered a severe test of 18th-century engineering skills, materials and construction techniques. For both designing and operating a water-conveyance transportation system through an area where sinkholes are common, and surface water is scarce. Ultimately, the 1794 engineering concept was flawed as the water supply for the summit crossing was inadequate and the technology for minimizing supply losses was still another several decades into the future. By 1796, however, the navigation company's project was a commercial failure. The result was that with the onset of the Erie canal still some thirty years into the future, Philadelphia lost the early initiative in water transportation.Hartman, J. Lee.

While credit was more plentiful than it had been for a half-century and the population growing ..."came increasing and insistent demands for ... improved transportation facilities." Regular tax revenues to the State were insufficient and could only be remedied by what seemed like at the time to be "abnormal increases in taxation." One remedy that had been used in the past was that of authorizing lotteries to raise funds, but only, for "important public purposes". In 1795, the State had authorized $400,000 for the Union canal's predecessor corporation, the Schuylkill & Susquehanna Navigation and Delaware and Schuylkill Canal companies. While there were numerous abuses of the lottery system in terms of complaints but the biggest problem was that of numerous "foreign" lotteries. Until the passage of the act for the "entire abolition of lotteries" by the State of Pennsylvania in 1833, "(F)oreign advertisements were to be found in nearly every issue of the county and city newspapers. They were especially evident after 1820, 324 Lotteries in Pennsylvania Prior to 1833. when it was not unusual to find four or more different foreign lottery advertisements in a single issue of a paper. During the entire period they were probably three times as numerous as those of lotteries chartered by the Legislature of Pennsylvania. In a single issue of the ''Greensburgh Gazette,'' on May 12, 1826, advertisements for the Connecticut State Lottery, The New York Literature Lottery, Maryland University Lottery, Mr. Jefferson's Lottery, The Grand Consolidated Lottery (New York), and only one Pennsylvania lottery, The Union Canal Lottery. Similar illustrations from papers throughout the state might be given. Many brokers in nearby states ran advertisements regularly in the county papers in Pennsylvania." But most importantly, the result was that "...many Pennsylvania authorized lotteries remained uncompleted or underfunded for years." :"The most striking illustration of this ...(problem with foreign lotteries) ... was the case of the lottery chartered in 1795 to raise $400,000 to aid in the completion of the ...(Schuylkill & Susquehanna and Delaware and Schuylkill Canals). After sixteen years, during which this lottery had schemes almost constantly before the public, only $60,000 of the $400,000 had been raised, due to the inability of the managers to sell their tickets." The most important single lottery in terms of number of tickets and in the value of prizes in the early history of state lotteries was the Union Canal Lottery authorized in 1811 but it was to be managed by the

and the Union Canal Company, respectively. The 1811 acts of authorization prohibited the use of any of the lottery funds as dividends paid to stockholders. The Union canal's incorporation permitted it to raise by means of a lottery $340,000, the exact amount that was left uncompleted by the predecessor companies in 1795. Between 1811 and 1821, even with this lottery effort, the company was unable to attract sufficient capital to complete the proposed canals and to keep them in repairs. In 1821, the legislature permitted the company to continue to raise by lottery for twenty-five years sufficient funds to enable the company to pay six percent dividends to stockholders. Between 1811 and December 31, 1833, the company conducted about fifty different lottery schemes and awarded in prizes more than $33,000,000. In 1832, the lottery paid $5,216,240.100.

The branch canal served as feeder for the summit level as well as allowing the transport of anthracite from the mountains, which became the principal revenue source for the canal operation. The charter of the canal company allowed it to build lateral railroad lines from the canal to reach coal mines. It built a line from the end of the branch canal to Lorberry Junction in 1830, which was operated by horse power. This connected it to the Lorberry Creek Railroad and brought coal traffic to the canal. In 1844, the track was leased to the Swatara Railroad, which extensively refurbished the

west of Reading. This portion contains one previously restored lock (Lock 49E) https://www.co.berks.pa.us/Dept/Parks/Pages/Stop6Lock49E.aspx along a towpath now used as a recreational trail. A portion of the canal along Swatara Creek is also preserved at Swatara State Park where there are remains of 7 locks, a towpath bridge, major sections of the towpath, and three dams are still visible in Swatara State Park. The canal was never rebuilt because the railroad soon went into operation on the opposite bank of the Swatara Creek.
