binds Us to keep the pavement in order for three
years; would not Law "a concrete pavement less
fhsn from II TO ID inches in depth; the ma
chinory necessary to complete our contracts in
tins city viii not cost less than SO O1; received
S295 per square yard Cor laying payementS
in this city; received nothing for con-
yard laid ought to be fifty cents per
ward; the cost of laying some pavement
isst tall cost us over 20 yard and We lost on the
contract; the contract price for laying concrete
pavement in Brooklyn is from s. to So 80 per
yard; dOn'tthink the ruling price Is less than So;
would not use cold tar in laying pavement; il
WCu'e not answer the purpose, for chemical rea-
sonS(which he explained al lengthy the sun would
destroy all the desirable properties in cold tar
In lew days; have seen an estimate by Capt
dFant Tor laying concrete pavement at ~ cts
a YARD; with travel on il such a pavement
would last about two months; Capt. Grant esti-
mates the cost of broken stone at So cents pei
yard; mine cost me twice as much; would Ike
70 get broken stone at Capt. Grants prices;
witness sand cost him s3.25, and came from
Pcoksville, n. Y; have seen the pavements
the agricultural grounds and naval ohserv atory.
IT Is honey-combed and will last but a short
time; witness was shown Thornton Smith =
opposition TO lay pavement for 15 cents 2
yard, ana was asked his opinion regarding Ii; he
said that 10 lay the broken stone alone he would
expect to pay 20 cents per yard instead of p, a.
estimated by Mr.. Smith; he had never vet been
able 10 get tar at 81 25 per barrel, which is the
pllce estimated by Mr.. $; q similar pavement
in 9th avenue, New York, lasted about eiyh
months; pavement but six inches thick o,
pennsylvania avenue would probably last sbou
the same time.
Gen. Chapman asked why witness pavemen
on l5k street had broken in seine places. and
witness thought a defective foundation the
cause; perhaps the compound was chilled when
luI on, and that fact might account for the
defect.
Gen. Chipman.-"Itha has been stated here aS N
evidence OF the wrothlessness Of the concret,
aHement that il breaks frequently. What il
Nn-iT opnion?"
Witness The fact that few breaks occur
!. Tar from being evidence OF its wOrthlessncss
The first year is the trying year for concrete
pavement. A breaks enables us to find out the
cause and to apply the remedy thus making the
pavement more perfect"
Gen. Chipman.-" IL your contract and that
OF John %. Evans in excess of prices generally
for laying the same kind OF pavement ?''
Witness. -'' No, sir. The feeling among con-
tractors generally is that prices in this city arc
lower than elsewhere"
MIR. CoOmbs said he had an appoiptm thi.
afternoon, and would like the witness TO com.
before the committee again next week. The
witness replied that he would be before the com
mlttee again on Wednesday next.

which has been thoroughly tested; laid a cen
crete pavement three inches thick on p
macadam bed, in Prospect Park, BROOKLYN.
which is better now than il was when laid.
By Gen. Chipman:-The idea of laying good
concrete pavement on Pennsylvania avenue at
ious; the rolling alone would cost half thar
amount.
BY Mr.. ACKNOWLEDGEMENTS pavements
have been laid in New York, Brooklyn and H.
Hartford 10 witness knowledge.
BY MIR. Chander:-The greatest care should
be taken in making the compound; it is yer,
important If good pavement il desired; nv
compound costs think, from 80 to 40 cents PEI
gallon.
