light, more daylight, than any other animal in the world. Because 

 when it goes up to tlie north for its summer home the sun is already 

 there and it has continuous sunlight throughout the four months 

 that it is there; then it goes south for the winter and by the time it 

 gets to the Antarctic the sun is also there and it has continuous 

 daylight for the four months it is there, so that it has daylight for 

 eight months in the year and part daylight for the other four 

 months. 



Now, in conclusion, T just have a few slides that I happened to 

 have on hand that I thouglit would be interesting. This shows a 

 robin's nest built on the top of a previous year's Baltimore oriole's 

 nest, using that as the foundation and building its nest on top. 

 This is the nest of the mallard duck, and it shows the down, you 

 all know the eiderdown; the mallard has the same habit of plucking 

 the down from its breast and laying it over the eggs when it leaves 

 the nest to keep them warm while it is gone. Thvire's a handsome 

 youngster; it is the great blue heron about six days old. I think this 

 is one of the most artistic bird pictures I have seen, this herring gull 

 just lighting down on the nest. And the last picture that T will show 

 is the humming bird, and I want to particularly call your attention to 

 a widespread misconception of the food of the hummingbird. You 

 hear about it and read about it as visiting one blossom after an- 

 other to get the nectar. As a fact, a hummingbird is not there 

 for that purpose at all. The food of the humming-bird are spiders 

 and it goes from one flower to another in order to eat the spiders 

 that are down in the bottom of the blossoms. 



SOME ORCHARD INSECTS AND THEIR CONTROL 



By F. H. FASSETT, Meshoppen, Pa. 



It may seem rather dull and dry after listening to such an in- 

 teresting talk on birds, to come down to the practical subject of the 

 control of insects in the orchard. It has been my endeavor for the 

 past 25 years to learn the best way and the best materials and 

 the best time to control these insects in my orchard work. There are 

 a number of different materials on the market that are being used, 

 and to my mind many of the spray bulletins and spray calendars, 

 without any criticism of these things, are misleading to the average 

 orchardist or apple grower because of the fact that they give us so 

 many remedies and so many different times of spraying that it would 

 lead one to believe that we must spray continually in the orchard. 

 We have found that for practical purposes of control of these insects, 

 that we believe we can control the insect enemies of our trees and 

 of our fruit with three sprays. There is, to my mind, a right time 

 to spray and a wrong time. If we can do our spraying just at 

 the right time, then we believe we can control so many more in- 

 sects than when we do it at some other time. For instance, the
