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."

CROTON AQ.UEDUCT. 201

No one will fail to be struck with the tone of natural solicitude evinced by the chief engineer in the close of this extract, for the due care and perservation of a noble work, on which he had expended so much time, talent, and anxiety, and by his connection with which he could not but feel, if more modest than the Roman poet, he did not say,

Exegi monumentum aere perennius * * * * * duod non imber er'ax, non Aquilo impotens Possit diruere, aut innumerabilis, Annorum series et fuga temporum.*

With regard to the permanency of the work and the probability on any great expenditures for repairs or additional securities, Mr. Jervis holds this language :

What now appears sufficient, may on further trial, develope the necessity of additional security. I am not aware of any indication, further than has been mentioned in the former part of this report, of the probable necessity of further security.Should, however, the appearance of water passing from the bottom of the distributing reservoir, as mentioned in a former page, show any material increase, or if it should not subside in the course of a few mouths, an additional course of concrete should be put over the bottom. I hope this may not be necessary, though it is proper for me to remark that I feel some apprehension that it may be expedient, as a prudential measure, to incur a further expense of twelve to fifteen thousand dollars for this purpose.
