lap is first turned up very carefully and all larvae located and crush- 

 ed, then the other layer is turned up and examined in the same way. 

 The two edges of the burlap are left turned up until next examined 

 for larvae when they are turned down one at a time and examined. 

 The bands should be examined once in every 7 to 10 days in 

 order that none of the larvae that go there may be able to come to 

 maturity and fly away. These bands may be a positive injury 

 father than a benefit if neglected and allowed to harbor insectis until 

 they mature. 



APPLE TREE PLANTING AND SPRAYING. 



Several hundred thousand apple trees are being planted in Mon- 

 tana each year and from observations made by the writer in various 

 parts of the state it is apparent that in many cases little or no at- 

 tention has been paid to so planting the trees that they may be 

 properly sprayed when they reach full size. It has been cleariv 

 shown in various parts of the United States that practically the 

 whole difference between success and failure in apple growing is 

 covered by the saving made through wise and thorough spraying. 

 Montana will be no exception to this generaly rule and when our 

 orchard industry, now in its infancy, has reached the development 

 that it seems sure to attain, various insect and fungous pests will 

 have become widely spread and will require systematic treatment. 

 The time is not far distant when in order to secure the best results 

 from the management of the commercial orchard it will be necessary 

 to spray several times each year. 



With these facts before us it is of the greatest importance 

 that in plantmg new orchards such a distance between trees be es- 

 tablished as will permit of passing around the tree with the spray 

 pole. It should at least be possible to drive a two horse wagon 

 through -between the rows of trees and to operate a spray pole be- 

 tween two trees in the same row without the interference caused 

 l)y tangling of limbs of different trees. It is a short sighted policy 

 that prompts a grower to set his trees close together that he may 

 secure a greater crop from the same acreage. This may be carried 

 to such an extent that the crop will be distinctly lessened rather 

 than increased, wholly independent of the benefits to be derived 

 irom spraying.
