tie which easily will go into the case with the glass over it, and 

 proceed in the same way as when using the lard can, only one 

 must be careful to gauge the quantity of the solution to the 

 size of the glass, as the least quantity overflowing when the 

 cyanide is dropped in will ruin pins and specimens with which 

 it comes in contact. 



The beetle giving me about the only trouble is Trogoderma 

 tarsale, which here seems to be two-brooded. The time that 

 I find most successful to exterminate their larvae is about the 

 first of May and the fifteenth of August. Perhaps a little 

 earlier for each brood would be as well, but in either case it

We didn't think it rained in Colorado in July and August,

 where. Our experiences during eight weeks in camp and field 

 were such that we thought somewhat seriously of offering our 

 services to the State as rain-makers, for it rained wherever we

The history of what befel us July i8th, 1902, in Colorado is 

 also exceptional, but there were other days no less moist and

It had rained the previous day, and cloudy weather had

 culinary duties, filled our pockets with the necessary boxes 

 and lunch and had started up the trail. What I have called a 

 gulch resembled a great basin with rugged peaks ascending on 

 three sides, some of them to a height of 12,000 feet or more. 

 These peaks all sloped back from the rim of the basin, and
