probation with which he has met, has 
been far beyond what was expected ‘fin 
any machine which could be worked en- 
tirely from below, over and above the, 
principal and important purpofe for which 
‘it was defigned, (that of preventing in 
future infants from climbing the flues,) 
the vaft quantity of foot it brings down, 
and great cleanlineis with which the ope- 
ration is per‘ormed, (where proper pre- 
caution is taken) have brought it very 
defervedly into great repute. One perfon 
is fufficient for performing the whele of 
the work with this machine, but it will 
be found very convenient to have an af- 
fiftant, to give up the rods from the 
ground, ard re-piace them” there when 
brought down. Thole. unfortunate litte 
creatures, whefe miferabk lot it has been 
heretofore to climb chimnies, may now be 
employed as afiifients for thefe purpofes, 
who, as they grow older, will become ca- 
p2ble of working the machines themfelves ; 
and, in‘tead of being turned off without. 
any employment when their apprentice- 
fhip is over, they may continue with their 
matters as ufeful hands. It appears from 
experience that about ninety nine chim-

by this machine, cccafionally ufing 
brufbes of different fizes and forms as 
civGumitanccs may require; and the re- 
maining few can probably be cleanfed by
