contrary finding to experience with the two mixtures in other districts, so 

 perhaps, while stating our experience, it would be well to try further 

 experiments. 



The Green Fruit Worm was quite noticeable in some of the orchards, 

 particularly those located near timber. These came on and did their 

 damage before the thinning of the fruit was completed so that by a little 

 care in thinning all the punctured or bored apples were removed. No 

 spraying was deemed necessary for these insects. 



The Leaf Miner {Tischeria) was quite noticeable in the orchards 

 near the timber line. These usually do so little damage that no means of 

 control are practiced. 



The Cicada, or called locally the Salmon Fly, did quite a lot of 

 damage to the young trees along the Columbia River by laying its eggs 

 in slits made in the young shoots, many of these shoots snapping off 

 later in the wind. 



The Climbing Cutworms were exceptionally troublesome this last 

 year. I have taken as many as 60 around one small tree. This was brought 

 about by an intercrop of clover having been plowed under in the spring 

 and the worms gathered around the small trees. In many instances 

 every single bud was eaten of? the trees. Poisoned bait was tried of 

 the usual strength, viz.: 100 lbs. Bran, 1 lb. Paris Green, and 2 lbs. of 

 sugar. No results were obtained. We next applied a stronger and 

 sweeter mixture with good results, viz.: 50 lbs. Bran, 1 lb. of Paris 

 Green and 3 lbs. of sugar. This seemed to be more palatable and the 

 worms preferred it to the buds of the trees, for on the following morning 

 after application dozens of dead worms were to be found around each 

 tree. The mi.xture should be applied fairly dry and crumbly and should 

 be sweetened according to the plants upon which the larvae are feeding. 



While on the subject of Paris Green baits for Cutworms it might be 

 well to sound a brief warning on the likely effect this bait will have on 

 young and tender plant growth. This last season has shown us that the 

 bait applied too close to the trunk, in fact, touching the trunk, is liable to 

 cause a girdling effect on the plant tissues. In a number of cases this 

 last summer our young trees were completely girdled from no other 

 cause than Paris Green injury. The larger trees do not suffer in the same 

 way, but it is reasonable to suppose that some evil results when 

 applied too close to matured wood. 



The California Tortoiseshell {Vanessn ca/ifornica)was found work- 

 ing in great numbers on the Ceanothus. They were particularly abun- 

 dant along the Columbia, Slocan and Kettle River sections. Many fruit 

 growers became alarmed at the outbreak, at the numbers and at their 

 ravages. However, as they kept to their own plant food and did not
