The prairie-planter needs a thin screen to break the force of 
the wind, both summer and winter; but if to the hot-bed soil 
of the prairie we add a close green-house atmosphere, we will 
have a luxuriant protracted growth of unripened wood, unfit 
for the extremes of our long winters. 
The southwest wind is the only one we need to protect 
from, as its extreme force, in the growing season, often mars 
t 
the tree and casts the fruit, and its extreme dryness in the 
spring is very exhaustive of moisture and vitality. Still it is 
questionable whether the winds from this quarter are*not pro¬ 
ductive of more good, in the main, than evil. Therefore, 
wliile I would urge to the utmost, entlmsiasm in timber-grow¬ 
ing, both deciduous and evergreen, on the prairies, to shelter 
and protect man and beast, I would caution against any 
course of culture or ‘protection which will defer or prevent 
that perfect maturity and hardiness which is the first need of 
the tree that must inevitably be exposed to the extreme of our 
climate. 
When the principles here named shall be fully understood 
and applied, then may we see success with tlie apple on the 
prairies, as on the poorer lands of the tirhber. 
The subject of revision of the apple list being under discTis- 
sion, a remark was made that certain trees were liable to 
APPLE TREE BLIGHT. 
Mr. Willey said that he had observed this tree blight, and 
had satisfied himself that it was the work of an insect. He 
had seen the apimal; and others could do so who would take 
the pains to hunt for it. 
Mr. Lawrenoe confirmed the insect view of blight, and de¬ 
scribed it as a small worm not larger than a small needle, that 
entered^ the wood on the new growth, at the base of the leaf, 
and descends through the pith, where it could be found. This 
causes the branch above it to die, and the immature leaves re¬ 
main on the tree during the balance of the year. He knew of 
no other remedy, except to cut off such limbs j ust below the 
worm and burn them, and thereby destroy the larvae. He had
