Sample bricks (6), from the Government Brick 
Factory at Acra. 
The following information, concerning the mann- 
facture of bricks and soorkey at Acra, has been 
furnished hy H. Dewes, Esq., C.E., the Exe 
cutive Engineer of the Acra Division : 
Immediately after the rainy season is over, that 
is in September and Octoher, the earth is dug and 
tlirown into lieaps in places convenient for pugging 
and moulding. The earth is then pugged in pug- 
mills, and carried to the tables, moulded in iron 
moulds, and the bricks thus moulded are taken to 
the “ hack ” or drying ground, and afterwards 
“ skintled.” The bricks wlien dry in liacks are set 
in clamps and fired. The bricks arc burnt in open 
clamps with coal. 
The sizes of clamps Vary from 50 feet square to 
70 feet square, the general size being 60 feet square 
at the base, and contains about 550,000 bricks. A 
60 X 60 clamp takes about three months to burn and 
cool. The rates of manufacture at Acra are given m 
the statement shown below. The men employed at 
thr Acra brick factory are principally from the pro- 
vinces of Orissa and Behar of the Bengal Presidency; 
very few from Bengal Proper. A good moulder wu 
mould from 2,000 to 2,500 bricks daily; some few 
will turn out as many as 3,000 daily.

Specimen of “ Soorkey ” (brick dust). 
Soorkey is used instead of sand to mix with lime 
to form mortar. The hroken bricks or bats from 
out-turn of clamps are conveyed by tramway, in 
trucks drawn by bullocks to the site of the soorkey 
manufacture shed, and there crushed by rollers 
worked by steam-power. The cost of manufacturing 
the soorkey per 100 cubic feet is about Rs, 9 in- 
' cluding the cost of bats, or Rs. 3 exclusive of bats. 
32,000,000 of bricks have been turned out at the 
factory in one season, butthe present yearly out-turn 
of materials is about 20,000,000 of well burnt bricks, 
and 300,000 cubic feet of soorkey, chiefly for Go 
vernment works in Calcutta and neighbourhood.

Model of the Sone anicut, head-lock, under sluices, 
head sluice, and half of the centre sluices. This 
model shows half of the head-works on the left 
bank of the river; the other half is exactly the 
same. The different parts of the head-works 
models are numbered so as to fit together thus : 
the arrangement of sluice gates opposite the centre 
sluices; the oblong foundation blocks, scaftoldmg, 
windlasses, and shallow-well excavator, opposite 
the anicut; the deep-well excavator and round 
well opposite the under sluices.
