GEOLOGICAL SURVEY OF THE TERRITORIES. 489 



geous display of the aurora borealis. It was first noticed about half 

 past eight o'clock iu the evening, when the northeast quarter of the 

 heavens was one glow of deep crimson flame. There was very little 

 shooting upward of narrow hands of light, but rather a gradual change 

 of color. Later in the night the northwest quarter became suffused iu 

 the same manner. 



The odometer has worked admirably, showing as the distance traveled 

 by the train 888.196 miles. This does not include the trips made by 

 yourself to the head-waters of the Chugwater Creek, Laramie Peak, 

 Box Elder Caiion, Uinta Mountains, the sources of Bear River, the 

 source of Henry's Fork of Green River, and Brown's Hole, which brings 

 up the estimate to 1,400 miles, making a daily average of about 18 

 miles. 



In conclusion, let me here add that my work in this department has 

 been attended with an increasing interest as the months have gone by, 

 and my only regret is that it is not more thoroughly done. 

 I have the honor to be your very obedient servant,
