On June 6, 1924, President Coolidge 
signed the bill establishing fishing reserves 
in Alaska and effecting other measures to 
conserve the salmon fisheries of the Ter- 
ritory; also prohibiting halibut fishing in

forest offers, these seeds germinate and 
grow very rapidly. Lodgepole pine is not a 
particularly valuable tree in itself, but as 
the savior of areas that would otherwise 
turn to brush-fields or barrens, it is an ex- 
cellent ally of the forester. Not the least 
of its virtues is its rapid growth averaging 
12 inches a year in height for the first 
fifteen years.

Mud Turtle Feeds on Sroutint Corn.--Mud turtles may invade cornfields and
com- 
pete with ground squirrels and moles in destroying stands of corn, according
to information 
that has come to the attention of Mr. Oman. A Riley County, Kans., farmer
reports that 
in the spring of 1928 he noted a mud turtle moving along a listed cord row.
Close inspec- 
tion and observation showed that the turtle rooted along, hog-fashion, to
find the sprout- 
ing corn.
