of similar habits, flying at night as most of our moths do, and 

 depositing her eggs on the under side of the leaf, these appear- 

 ing in a flat greenish cluster, covered with a white bloom. 



This picture represents the pear covered with the so-called 

 San Jose scale — a pest that has not reached Maine to any extent 

 although this summer we have discovered it in three new sec- 

 tions. Before we have only known it to be in one orchard in 

 the town of Limerick where it has existed for eight years, and 

 there by proper spraying and treatment this year we think we 

 have controlled it. While inspecting a Gregory orchard the 

 other day my assistant found a tree infested with the living 

 scale. A report has come to me of a tree infested at North- 

 east Harbor, and I found one in Gardiner this summer. These 

 last were both dead. Although we have not formerly had this 

 pest, while our neighboring states have been badly infested, we 

 must be on the watch to destroy it, for it is the w^orst pest that 

 can come to our orchards. 



We now come to the brown-tail that has been mentioned 

 tonight, a caterpillar that infests Maine more than any other 

 New England state. Coming first to Massachusetts, it spread 

 to Maine and today we have over 8000 square miles in- 

 fested with this insect pest. It is, as you learned, easily con- 

 trolled in the orchard. You never need have a single fall or 

 winter nest of brown-tails if you treat your orchards properly 

 by spraying with lead arsenate toward the end of July or the 

 first of August, directing the spray on the under side of the 

 leaves. You will then destroy the little fellows before they 

 make their winter nests. 



The next slide will show a cluster of the adult moths, the 

 male and two females. The next shows the female in the act 

 of finishing the cluster of eggs, a brownish deposit about the 

 width of an ordinary lead pencil and from an inch to an inch 

 and a quarter in length. This egg cluster may be found if you 

 examine your orchards in the latter part of July. 



Now pass from these pests to another condition in Maine. 

 The winter of 1906-1907 has been referred to as being the cli- 

 max of injury to Maine orchards. The condition shown here 

 is of an orchard of perhaps four hundred trees, the picture 

 being taken, as you see, in the summer time, and yet there are 

 no leaves on the trees; an orchard completely destroyed in
