Passing under bridges, over rivers, between high embankments, and through deep cuttings, floated up hill by a series of locks, he marvelled at this triumph of engineering, and, if he were a director, pictured the manufactories that were to spring up along this great thoroughfare, swelling its revenues for all time. The tow-path of the canal was a famous promenade. Upon Sunday afternoons, especially, numerous pedestrians from the dusty city strolled along the canal for a breath of fresh air and a glimpse of the open country, through the Royal estate in Medford, past the substantial old-fashioned mansion-house of Peter C. Brooks, as far, perhaps, as the Baldwin estate, and the birthplace of Count Rumford, in Woburn. "I love that old tow-path," said Uncle Joe. "'Twas there I courted my wife; and every time the boat went by she came tripping out to walk a piece with me! Bless you, sir the horses knew her step, and it wan't so heavy, nuther." Meanwhile, under the direction of Caleb Eddy, who assumed the agency of the corporation in 1825, bringing great business ability and unquenchable zeal to his task, the perishable wooden locks were gradually replaced with stone, a new stone dam was built at Billerica, and the service brought to a high state of efficiency. The new dam was the occasion of a lawsuit brought by the proprietors of the Sudbury meadows, claiming damages to the extent of $10,000 for flooding their meadows. The defendants secured the services of Samuel Hoar, Esq., of Concord, assisted by the Hon. Daniel Webster, who accepted a retaining fee of $100 to "manage and argue the case in conjunction with Mr. Hoar. The cause was to have been tried November, 1833. Mr. Webster was called on by me and promised to examine the evidence and hold himself in readiness for the trial, but for some time before he was not to be found in Boston, at one time at New York, at another in Philadelphia, and so on from place to place so that I am satisfied no dependance can be placed with certainty upon his assistance, and," plaintively concludes the agent, "our $100 has gone to profit and loss account." On the other side was the Hon. Jeremiah Mason, assisted by Franklin Dexter, Esq. This case was decided the following year adversely to the plaintiffs.
