especially if the English grown tobacco is used, as it is not so 
strong as the Foreign grown : then charge the tube, leaving 
room for a few hot cinders to lie on the top of it ; after the 
tube is fixed in the socket or lid, the bellows must be played 
to force out the smoke, as it may be required. *1 o free the 
operator from the common and unpleasant situation of be- 
ing involved in smoke, while in the act of performing the 
operation, a hole of a proper size to admit of the pipe only 
might be made at each end of the house, and middle, or in 
more places, according as it is thought necessary, from the 
size of the house. Care must be taken not to play the smoke 
closely upon any of the plants, as it would prove injurious 
to them. 
REMARKS ON SHREDS, 
USED IN FASTENING WALL TREES. 
In all cases when shreds are intended to be used again, 
they must be put for a few minutes in boiling water, also any 
branches that are used for protecting blossom of fruit trees, 
or any other materials used about them, likely to be infested 
with insects in the spring should be immersed in boiling 
water a few minutes, in order to destroy the eggs or insects 
that may be there lodged. Here I may observe, that it is 
preferable to use shreds of cloth to any other mode that is 
practiced for training trees, as they form harbours for insects, 
through the winter, and afford a good opportunity for the 
insects and eggs of insects to be removed with the shreds, 
and destroyed with boiling water. This is contrary to the 
opinion of many, who say those shreds harbour insects, and, 
therefore, band or mat is recommended in preference, as 
they afford no protection to them. It must be allowed if 
there are no shreds to afford protection to the insects they will 
have other resorts, and, therefore, if they be in existence it 
matters not whether they have harboured in shreds, crevices 
of the walls, or trees, under stones, in tlie earth, or in other 
retreats, when their existence is not prevented.
