THE OOLOGIST 



The reasoning of the purple gracklo 

 is remarkable and illustrates in a 

 marked degree the unusual intelli- 

 gence of the birds. 



My friend says the "blackbirds" de- 

 stroy many walnuts every year in 

 this way.

List of Birds Found Breeding in the 

 Titanic 



Mountains and foothills around Boul- 

 ter on the line of the Salt Lake Route 

 to the coast, 98 miles south of Salt 

 Lake. Altitude about 6000 feet at 

 Boulter, highest point above Dry Lake 

 9 miles N. E. of Boulter 9000 feet, and 

 a field full of variety for the collect- 

 ors. Notwithstanding its arid surface 

 of three by nine miles having but one 

 spring of water. 



Its lower zone a bunch of hills vary- 

 ing from 50 to 250 feet, more or less 

 covered by stunted cedars and pinon 

 pines, intervening ground covered by 

 a fairly good growth of sage brush, 

 peopled by coyotes and jack rabbits. 



Then we come to an intermediate 

 zone of gentle slope to the foot of 

 mountains proper, which are quite 

 abrupt, and in many places covered 

 on the south and west faces with 

 cedar, mahogany and pinons. On the 

 north face we find spruce, fir and a 

 few hemlock, while at the upper end 

 of the canons we find litle park-like 

 mesas with aspens. 



I have given this description so 

 that my notes may be more fully un- 

 derstood, and shall segregate the 

 birds in zones, as it is more conveni- 

 ent for me, at least.
