Four blocks of the land required for the receiving reservoir, containing about 4f acres each, were obtained by purchase, and application was made to the Chancellor, for the appointment of appraisers, on whose award the remaining lands might be taken. A circular was also addressed to the chief iron founders in the United States and Great Britain, inviting proposals for the iron pipes that would be required for syphons, and for connecting the receiving, with the distributing, reservoir. These pipes, for the most part, were to be 3 feet in diameter, and others 30 inches, varying in thickness, from one to one inch and a quarter each. The whole weight was estimated at from 4 to 5000 tons. This timely notification was given, to the end that it might be ascertained, whether it was best under all the circumstances of the case, to these or obtain import pipes, them at home. In order to keep the progress of the work before the reader's eye, we copy from the Commissioner's Report of July, 1838, the statement of what had been accomplished since the previous report.

The work performed during the winter consisted, principally, of excavation of earth and rock, in tunnelling, and in quarrying stone, and preparing them for use in the construction of the culverts, bridges, and other erections connected with the aqueduct, which has greatly facilitated the spring operations. But, in order that some idea may be formed of the progress of the work, we beg leave to present the following statement, embracing the principal operations on the line ; such as the length of aqueduct completed, the number and extent of tunnel excavation, the number and capacity of the culverts erected, &c. :
