At the same time it should be distinctly urged that economy or efficiency, can only be expected, from the supervision and care of men, who are intimately familiar with the method of construction and the character of the work, and who will deeply feel the high responsibility confided to their industry and fidelity. The main burden of this duty will consist, in an unwavering perseverance watching;

with scrutinizing care every part of the work, and seasonably providing for, and making such repairs as may be necessary. The extent of the work, the variety of its structures, the severe pressure to which many of its parts are necessarily exposed, and the great importance to the city, in maintaining it in a condition that will ensure a regular and full supply of water, must give to every reflecting mind, a strong sense of the high responsibility that will rest on those to .whose care it is confided. Not expecting to be much longer engaged in the general charge of the work, I have felt it to be a duty that I owed, not more to my own reputation, than to the interest of the city in this great work, to urge the above remarks in relation to its future management."
