The thickness of the cast-iron pipes given in this table were calculated by
the following formulas:
For diameters greater than 36 ins., t = .00003 II D + .0125 D + .33; for di-
ameters of 36 ins. and less, t =.03003 H D + .01 D + .30; t = thickness in decimals
of an inch; D = diameter in inches; H = head in feet.

The thickness of the Class A pipe was based upon a static pressure of
10(> ft., and the Class B pipe upon a static pressure of 180 ft.
The figures include the cost of pipe, gates an I " specials," the cost of cart-
ing, laying and setting, and excavating and back-filling for the same, and all
other expenses generally incurred in ordinary water pipe laying, with the
exception of the cost of hydrants.
The cost of "specials" was based upon $0.025 per pound, with pipe at
$30 per ton, the cost of air-cocks (used only with pipes having a diameter
larger than 20 in.), at $10 each, and the cost of the gates the same as given in
Table No. 3.
Ordinary labor was considered at $1.50 per day.
Depth of Pipe.— The depth of the axis of the pipe below the surf ace of
the ground has been considered in all cases as 4.67 ft.

This table, No. 5, contains the items in detail from which the cost of the labor
of laying water pipe, from 4 to 24 in. in diameter, given in Table No. 3, were
obtained.
The word "Trenching" is used for excavating and back-filling.
Throughout these tables Easy Digging is intended to correspond to exca-
vation in sand, etc.; Medium Digging to excavation in sand and gravel, etc.;
and Hard Digging to excavation in hard or moist clay, etc. The figures relat
ing to medium excavation are probably the most reliable for pipes that have a
diameter greater than 8 ins.
The prices given in any of the tables do not include the cost of engineering
and inspection.
SUPPLEMENT TO TABLES NOS. 2, 3, AND 5.
The following table gives the items of the actual cost of the labor of laying water pipe
ana excavating and back-filling for ihe same, upon which Tables Nos. 2, 3 and 5 were
based, with, the exception of the cost of carting pipe, which was considered at $1.00 per
ton. The table also shows a comparison of the items of actual cost with the amountx
that correspond to them in Tables Nos. 2, 3 and 5. The tabl" was computed from rec-
ords kept in Providence, with the exception of the data that refers to the 48-twc/i pipe,
which was obtained elsewhere.

In this table, under the division headed "At $0.30 per Cubic Yard," the cost
per lineal foot of Trenching, etc., is based upon the excavation at $0.30 per
cubic yard, measured in the trench, instead of the actual cost, and takes the
place of the amounts charged in Table No. 5, for medium digging, to trench-
ing, teaming, and % the amount charged to foreman and tools, etc. (ex-
clusive of the cost of blocks and wedges, which are included in the cost of
Tools, etc., for 24-inch pipe, in Table No. 5). The figures relating to laying, etc.,
are the same as those charged in Table No. 5 for medium digging, to laying,
calking, lead, carting, and % the amount charged to foreman and tools, etc.
(exclusive of the cost of blocks and wedges, which are included in the cost of
tools, etc., for 24-inch pipe, in Table No. 5). In each instance, in calculating
the cubic contents of the trench, the width was considered as 2 feet more than
the diameter of the pipe and % of a foot deeper than the water line of the
same.

The cost of a square yard of broken stone £ ins. thicfc, put properly in place
in a street, would be about $0.40.
The figures in this table were based upon a trench 3 ft. wider at the surface
of the ground than the diameter of the pipe, in order to allow for caving, etc.
The cobble stone paving was considered at $ 0.30 per square yard, the
granite blocks laid upon sand foundation at $0.45 per square yard, and the
granite blocks laid upon a concrete foundation, etc., at $3.46 per square yard.
The granite blocks were estimated to lay from 24 to 27 per square yard.

AHERICAN RAILWAY JOURNAL
Published every Thursday at Tribune Building, New York.
23d Year. Five Dollars.
Engineering News contains each week twenty-
four pages of valuable reading matter, cover-
ing the entire field of engineering science in both
this and foreign countries. Railways, water-
works, bridges, manufacturing and technical, con-
tracting, mechanical and electrical industries are
fully reported, and detailed working drawings
and full descriptions are given of all the more im-
portant and note worthy structures and enterprises.
Record is kept of the proceedings of the engi-
neering and technical societies and clubs, and the
latest technical books and magazines are fully re-
viewed and discussed. The correspondence col-
umns contain communications from engineers,
contractors and others, regarding matters of cur-
rent interest.
The advertising columns and those of "Con-
struction News" constitute the most complete rec-
ord of the current contract work of engineering
in the United States that is obtainable. Together
they make a very complete index of new rail-
roads, new water-works, sewer building, street
paving, highways, river and harbor improve-
ment, bridge construction, public buildings erect-
ed, tunneling, pile driving, dredging, blasting op-
erations, experiments and actual work in concrete
and cement, electricity and gas, artesian wells,
canals, everything, in fact, having any relation to
public work, or the business of civil engineering
and contracting, while from the abstracts of bids
published from week to week, the prices of labor,
materials and other elements of cost of engineer-
ing work in different parts of the country are ob-
tainable.
