where there were plants between the rows which interfered with 
moving the cloth. In putting on the second piece of tent cloth it 
should lap over about two feet at the top so as to make a tight joint, 
to hold in the smoke. This piece is drawn over the frame and held 
in place by two smallropes. Each piece of tent cloth is big enough 
to reach half way around a tree spreading sixteen feet and the frame 
and allow a liberal amount for a fold at the ends, where the two 
pieces are fastened with safety pins. It is not necessary that the’ 
frame should cover the whole tree but that it should come up high 
enough to hold the cloth,so that it may be drawn over the branches. 
In smoking we used a common greenhouse fumigator, as shown in 
figure 6, but any iron pail with holes near the bottom will answer 
the same purpose. It required about five minutes ; 
use of the smoker to fill the tent full of smoke, after 
which the smoke was kept confined for from ten to 
fifteen minutes before the tent was removed. It 
took less than ten minutes to move the tent from 
one tree to the next and to set it up ready for the 
smoke, or something less than half au hour for 
each tree for the complete operation. It required 
at least three men to move the tent to best advan- 
tage. While the smoke was being held in the tent,the (Fig. 6.) 
men in ourcase found employment at hoeing the small fruits and 
shrubs between the trees. In casea large number of trees were to 
be smoked, the use of three tents would keep the men busy all the 
time, and I think the cost per tree could be reduced to about eight 
cents. In this case the cost was about twenty cents per tree. In 
our case also the cloth used was two stock covers, but heavy cotton 
cloth would answer just as well. 
The frame, the management of the tent cloth and the fumigating 
can are shown in the illustrations. The material used for smoking 
was tobacco stems, which we obtained here free of expense from 
cigar factories. In using the fumigator, or smoker, care must be 
taken to keep the stems from blazing, or the tree may be injured. On 
this account,itis well to have the stems slightly moistened. We found 
that after putting up the tent and filling it so full of smoke that one 
could not see through it and leaving it for fifteen or twenty minutes, 
all lice would be killed and fall to the ground, often completely cov- 
ering the ground under the trees.

The past season has been unusually favorable to the healthy 
growth of both orchard and nursery, and although an off year for 
fruit we have gathered about 100 bushels from our home orchard of 
eighty trees. 
Blight leaps over dozens of other varieties in the nursery and 
descends upon a few short rows of Transcendent crab, situated 
about the centre of the nursery, and nearly destroys them; the 
same is true of the Russian Aport and Transparent in the orchard.
