FLY-PAPER FOR ORCHARDS.

Tho fact that insects injurious to orchards may he carried great distances by wind has recently been proved by a novel 'method. To prove that spraying an orchard does not in..arc against the ravages of the red spider, E. E. Munger, of Yuba City, California, used sticky flypaper to catch the insects, which lie believed were blown great distances by the wind. The results showed that the air may be literally full of the pests to a considerable height, from the ground. In the first test he placed a, sheet of sticky fly-paper on a post 20 feet from an infested tree. In 24 hours the paper was covered with red spiders. The next test was made with the paper 12 feet from the ground and 100 feet from the tree. The results were the same. Sixteen sheets of fly-paper were tacked to a fruitdrying tray and mounted on top of a step-ladder, which was set in cans of oil to make sure that no insects could crawl on to the trap. This was placed 650 feet from the orchard, and the next day spiders were found in abundance. It has been known for some time that the insects that infest orchards might be transmitted from one tree to another by the wind, but proof was not at hand before to show that the insects could be carried such a distance as this.
