The minimum temperatures recorded for the Koyukuk district at Coldfoot are 

 reported to be —S0° and even lower, but the instruments on which these records are 

 based are not known. It is hardly to be supposed, however, that it becomes much 

 colder here than at Circle, Dawson, and other points on the Yukon. Though grass 

 and other feed was scarce, a horse is reported to have wintered at large on North 

 Fork of the Koyukuk, on Mascot Creek, in 1902-3, and appeared to be in fair 

 condition in the spring. 



ARCTIC PLANTS COLLECTED. 



The following plants, collected on the trip mostly lyy G. H. Hartman, have been 

 identified, with the exception of the grasses, by Frederick V. Coville and W. F. 

 Wight, botanists of the U. S. Department of Agriculture. The grasses were identi- 

 fied by Mr. Elmer D. Merrill. The localities of collections are designated by camp 

 dates, which latter will be found on the topographic and geologic maps (Pis. II and 



III).
