134 ZOOLOGY— lUKDS. 



All such notes have been made available, and in each instance will be found 

 accredited to its proper source. In 1872, the months inclusive from July 15th 

 to December were spent in the field, during which time over six hundred 

 birds were collected by Dr. YaiTOW and myself, including one hundred and 

 sixty-five species. The route taken was a varied one ; but, in general, the 

 line of travel may be stated as a southern or southwestern one, from Salt 

 Lake City to Saint George, the exti-eme southwestern settlement in the Terri- 

 tory. Many of the lines of travel led over plains of sage-brush and wastes 

 of sand, remarkable for little else save the desolate character seen in every 

 feature of the landscape and the paucity of animal life. In the neighborhood 

 of the streams, however, where vegetation always grows luxuriantly, and 

 especially in the vicinity of the towns, birds were found in considerable luun- 

 bers, and often the number of species was considerable. The mountains, too, 

 furnished some interesting varieties, though less time was spent among them 

 than would have been desirable, since it is in the more elevated regions that 

 the heavy growths of forest and profuse vegetation, attain their greatest 

 luxin-iance, dependent as they are almost entirely upon the amount of annual 

 rain-fall, which, in the high mountains of these regions, is very considerable. 



In 1874, the time was spent in sections of country far more favorable 

 to the successful prosecution of zoological Avork in general, while certain 

 points proved especially interesting to the ornithologist. As a result of the 

 season's labors of Dr. Rothrock, Dr. Newben-y, and myself, more than two 

 hundred species of birds were obtained, included in an aggregate of very 

 nearly twelve hundred specimens, many of which were of great rarity, and 

 one {Eugenes fulgens) new to our fauna. Others also were noted, and their 

 identity ascertained beyond doubt, of which no specimens were secured. 



The following brief resume of the season's work, indicating the points 

 where any considerable intervals of time Avere spent, may prove of interest. 



In accordance with orders received, I made an early start, and ari-ived 

 in Denver the 5th of May, 1873, intending to proceed directly to Fort Gar- 

 land, Col., a locality which had been selected as affording a promising 

 field for zoological work, more especially in ornithology. Through the 

 unavoida])le detention of my collecting material, my stay in Denver was 

 prolonged f«>r more than two weeks. I'his interval (ill the 2-_M of May
