POSSIBLE EFFECT OF TH PRESENT COLD WINTER UPON CROP DAMAGE 
BY INSECTS NEXT GROWING SEASON.

the rest were gifts. The policy of the Association is to look to donors for 
fiction and miscellaneous light reading and to spend the money it has raised 
On more serious books. The Association will not attempt to administer directly 
the books it will send to France. This work will be handled by the Young Men's
