tube or ‘box, the upper end of which is 
®pen, and the lower end grated with 
thin bars, or with a bottom perforated 
vith numerous holes. In‘ this box is to 
be placed coarse gravel, pebbles, &c. 
‘which will leave a passage for the smoke, 
as a sort of strainer. The smoke passing 
through this strainer, and depositing 
part of its soot, the strainer must be 
occasionally removed to be cleansed. 
Eiehthly, aSoot-trap Stove is described 
by the Doctor upon the same principles.. 
The advantage of which, we are told, if 
properly managed, will so far diminish 
the collection of soot in chimneys, that 
they will very seldom require to be 
Swept: the danger of fire in a chimney 
thus’ constructed will’ be nearly done 
away, and the smoking of chimneys in 
many cases prevented. — v4 , 
Ninthly, a Chimney Water-trough is 
intended to produce the’ sane desirable 
effects. The chimney being stopped as 
before; from the back edge of the plate 
or slab, let a ledge descend a few inclies, 
under which a metal trough is to be 
placed-so ‘as to fit the breadth of the 
chimney, and to present an opening of 
two or more inches in front and rear of 
the descending ledge. The lower edge 
of the ledge is to be exactly horizontal, 
to form a parallel ne with the water in 
the trough, and it is to descend so low, 
that if the trough were filled with water, 
the liquid would entirely stop the passage.

The trough is to be supplied with water 
from a reservoir by means of a ball cock, 
and it is to be emptied, when necessary; 
through a pipe and cock placed at the 
bottom for the purpose. f 
Tenthly, a Chimney-damper, consist- 
ing of a double hair or woollen cloth 
large enough to cover and close the 
opening of the chimney, and which 1s'to 
be applied wet, in case the chinney 15

The last things described by the paten- 
tee area Water Candlestick and Candle. 
A pan, basin, &c. of six or more mches 
deep is to be furnished with a socket, 
the top of which is at least half an inch 
lower than the margin of the pan, and 
the diameter of its bore ‘proportioned to 
the size of the candle intended to be used. 
The socket to have one or more holes 
near the bottom to let the water pass 
freely. Let water be poured into the 
pan until it rise about an eighth or quar- 
ter of ‘an inch above the top of the 
socket; and the candle is to be thicker 
in proportion to the wick thah common 
candles. ; 4 Fea, 
Such are the outlines of the specifica- 
tion before us: some of the principles con- 
‘tained in it ‘certainly have not that sort 
of claim to novelty as to give Dr. Carey 
an exclusive title to the use of them, and 
we doubt very much as to the utility 
and practicability of others.
