was reabsorbed in an hour or so, carry¬ 
ing back whatever cement it might 
have originally brought up with it, so 
there was certainly no loss of binding 
property incident to the process. 
This particular concrete, which was to 
be used for underpinning a heavy build¬ 
ing, was purposely mixed very dry, so as 
to allow of the utmost possible compres¬ 
sion by tamping. For ordinary pur¬ 
poses, in our opinion more water might 
be used without disadvantage, but it is 
difficult to conceive of circumstances 
under which concrete footings could 
be properly made with less water. It 
is hardly necessary to say that the 
slight film of water which adheres to the 
surfaces of broken granite after washing 
would be ridiculously inadequate for 
moistening the quantity of dry sand and 
cement necessary to fill the voids in the 
mass; and that concrete made in the 
manner proposed by the “Engineering 
Record’s” correspondent would be a 
mere incoherent heap of loose cement 
and sand, containing lumps of a very 
imperfect matrix, each with a bit of 
granite for a nucleus .—The American 
Architect and Building News. 
LONDON’S SOOT 
/ T V HE amount of carbonaceous and 
other particles deposited upon 
glass houses is a good indication of what 
the London atmosphere contains, and in 
many cases it is only possible to procure 
a due admission of light to the plants by 
frequently washing the glass roofs. At 
one establishment, says the “ Phar¬ 
maceutical Record,” two tanks con¬ 
structed to collect the rain from a house 
completed a few years since, were cleared 
out, and no less than ten barrow-loads 
of sooty matter were removed, all of 
which must have been conveyed into the 
tanks from the glass. One scientific 
man has been engaged in computing the 
amount of soot deposited from London 
air, and arrives at the following con¬ 
clusions. He collected the smoke de¬ 
posited on a patch of snow in Canon- 
bury one square link (about eight inches) 
in extent, and obtained from it two 
grains of soot. As London covers i io 
square miles, this would give us for the 
whole area 1,000 tons. As the quantity 
measured fell in ten days, a month’s 
allowance would need 1,000 horses 
to cart it off, and these stretched in a line 
would extend four miles.
