make great deal by such result and the city, under the
contract SYSTEM would in such case be paying great

beg to suggest to tho Honorable Body therefore, since
an objection Is entertained to complete the whole work
by days wo H. to provide for the doing Of 80 much as
may relate to tho removal Of all tho difficulties by the
dav system of work. and make your contract for the con-
tnuation of the boring the we'll to the depth
qured by the contract system. From what have said
think it will appear very evident to your Honorable
Body that my suggestion has something recommend it
to YOUR favorable consideration.
The system Of contract prevails in France particularly
and mostly for wells not over 800 to 1000 feet In dcpth
