3Iaterials fur the Construction of Cottages.

had the strongest objection to tlicrc being a third bedroom ia a 
labourer's cottage, because it often led the cottager to receive that pest 
and nuisance — a lodger. Mr, Taylor had not given the dimensions of 
the rooms. 
Mr. Taylor explained that he jn-efaced his remarks by saying that 
he had not come there to show any particular plan of cottage-buildings. 
Had he done so, his statement would have been most incomplete unless 
it included an estimate of what the cottage might be built for ; and 
estimates were generally so fallacious that he was quite sure that would 
have done no good, and no one would have given him credit for accu- 
racy. His object was, therefore, simply to show improved and cheap 
modes of constructing cottages ; and with that view he mentioned fom* 
special points for consideration— the foundation, the walls, the roofing, 
and the paving. Any gentleman who wanted to build a cottage might 
ascertain for himself how much a yard he would have to pay for con- 
crete on the spot, and what would be the cost of bricks. It was calcu- 
lated that a rod of ordinary brickwork would require 4352 bricks, 
which, at 32s. per thousand, would cost 11. On the other hand, a rod 
of the patent walling v/ould require 1450 bricks, which, at 20s. per 
thousand — that being tlie j)rice for laboui-ers' cottages only, in which 
case he charged no royalty — would cost 11. 16s. 3d. Add to this the 
cubical contents of the concrete required, namely, 9^ yards, at 16s. ^d. 
(taking the gravel at 2s., and the lime at 10s.), there was 11.. 12s. 8cZ., 
making a total of 8?. 8s. llcZ. per rod of 14-inch work, as against 11. 
per rod of brickwork. In this calculation it was assumed that there 
would not be more than the ordinary amount of expense for convey- 
ance. The materials might be made on any estate where there was 
plenty of good clay. 
He had spoken of the cost of materials only, assuming that the 
cost of scaffolding, labom*, &c., would be about the same as v/ith 
ordinary brickwork — neither more nor less. 
As to the weight of patent brickwork, the materials are, in fact, 
so light that almost enough to build a cottage might be sent in a 
railwp.y truck ; 4350 common bricks would weigh 9 tons 14 cwts., 
while 1450 of his patent bricts would weigh only 1 ton 9 cwts. Thus 
it would be seen that the cost of carriage in the case of his 
materials was exceedingly low. His patent roof tiles weighed 
about 656 lbs. per square ; plain tiling weighed about 1624 lbs. per 
square. Pantiles would generally weigh about one-half. A roof 
so constructed might possibly be colder than an ordinary roof ; but 
an air-tight roof he considered unhealthy. One great object is 
ventilation. The clay of which tiles are made is frequently so porous 
that water would filter thi-ough it ; and it is well known in tile-making 
districts that a porous tile would withstand the action of frost better 
than one which is non-porous. If they wished to have a perfect tile- 
roof, they should take care that the tiles were porous. 
He had shown that paving on his principle would be drier, and 
th.crcforc warmer than ordinary paving ; and with that paving there 
was no necessity for the sleepers and brickwork required under a 
wooden floor. The gentleman who thought that cottages must cost
