placing the logs in water and burning the 
branches and tops; or (d) by removing 
the infected bark from the trunks or logs 
and burning it with the branches or as 
fuel. 
5. So far as combating the beetle is con¬ 
cerned it is unnecessary and a waste of 
time to dispose of trees or branches which 
have been dead twelve months or more, 
because the broods of the destructive bee¬ 
tle are not to be found in such trees. 
6. Spraying the tops or branches or the 
application of any substance as a preven¬ 
tive is not to be recommended. Nothing 
will save a tree after the main trunk is at¬ 
tacked by large numbers of this beetle or 
after the bark and foliage begin to die. 
7. The injuries to the twigs by this 
beetle do not require treatment. 
8. The bark and wood of dying and 
dead trees are almost invariably infested 
with many kinds of bark and wood-boring 
insects which can do no harm to living 
trees. Therefore all efforts should be 
concentrated on the disposal of the broods 
of the hickory bark beetle, according to 
the above recommendations. 
In order to insure the protection of the 
remaining living trees it is very important 
that at least a large majority of the dead 
infested and partially dead infested trees 
found within an entire community of 
several square miles, be disposed of within 
a single season to kill the broods of this 
beetle. Therefore there should be con¬ 
certed action by all owners of hickory 
trees. 
On account of the value of the hickory 
for shade and nuts and for many com¬ 
mercial wood products it is important that 
the people of a community, county or 
State who are in any manner interested 
in the protection of this class of trees, 
should give encouragement and support 
to any concerted or co-operative effort on 
the part of the owners towards the proper 
control of the hickory bark beetle. 
Growing Mushrooms 
V ALUABLE suggestions on the grow¬ 
ing of mushrooms are given by 
Prof. A. G. B. Bouquet, vegetable garden 
expert of the Oregon Agricultural Col¬ 
lege. Those afraid of ‘‘toadstool poison¬ 
ing” need have no fear if they follow his 
directions. 
“The kind usually grown commercially 
is the Agaricus campestris,” says Prof. 
Bouquet. “The color of the gills (the 
under surface of the cap) is creamy white, 
turning later to a pink, and in some brown 
varieties to a grayish brown, and later still 
to white. 
“The common causes for failure in 
mushroom growing are the use of poor 
spawn or spawn killed by improper stor¬ 
age ; spawning at too high temperature; 
too much water at spawning or later; and 
improper preparation of the bed. One of
