Extract

In November, 1930, spruce stands throughout a great deal of the interior of the Gaspe peninsula were found to have been partially defoliated by a sawfly. In some areas the greater part of the foliage had been eaten; about ten cocoons per square foot were found in moss and litter on the ground, beneath the trees.
