FEEDING THE WINTER BIRDS 257 



on a wire. The details of this have been worked 

 out very ingeniously by Edward Uehling, who, at 

 the time this work was done, was a boy in the eighth 

 grade of school. The author was closely associated 

 with him in this work and tried a similar device at 

 his own home. Some of the most successful results 

 of which the author has known followed .from this 

 plan as worked out by his friend during the winter 

 of 1906 and 1907. A wire was put up, sloping from 

 a second-story window to a tree about forty feet dis- 

 tant. On this wire the lunch counter was sus- 

 pended by means of two pulleys set in a frame. To 

 this frame a string was attached and run to the win- 

 dow. The slope of the wire carried the counter to- 

 ward the tree, so that it could be kept in any desired 

 position along the wire. On this were placed suet, 

 nuts, sunflower seeds, and other foods. At first this 

 was allowed to remain out at full length of the wire, 

 touching the tree. Tree-climbing birds soon found 

 this and came regularly to feed upon it. After the 

 birds had become accustomed to coming to the 

 counter in this position, it was drawn up a little 

 nearer each day, till at the end of a month it had 

 been pulled to the window. Those birds which at 

 first came to it continued to do so even when it was 

 brought up near enough to touch the window. The 

 following winter a roof was placed over the trough, 

 which partially prevented the food from being cov- 

 ered by snow during storms.
