110 THE NAUTILUS. 



well paid for the time spent. I also fouud Pyramidula striatclla 

 cronkhitei Newc. and Conulus fuhus alaskensis Pils. Associated 

 with these were two shells that Mr. George H. Clapp and Mr. H. A. 

 Pilsbry considered new, and were kind enough to name in my honor, 

 Zonitoides randolphi Pilsbry and Clapp. At the head of the lake, 

 near our camp, the rocks were covered with Valvata sinccra Say and 

 Lwin&a palustris Mii.ll. 



The next day we put together our canvas boat, made of twenty- 

 ounce duck, ready for our 600 miles trip down the Lewes ;md Yukon 

 rivers to Dawson. At Marsh lake found dead shell* of Linnnwt ampla 

 Migh., some very large, one measuring one inch uuu a half long and 

 one inch 'across, and a dwarf variety of Limnxa pnlustris Miill. 



The only shell collected going down the Lewes river was Succinea 

 nuttalliana Lea. 



We ran the famous Miles canon in our canvas boat, but packed our 

 outfit and boat around the White Horse rapids. 



I had no further opportunity for collecting until we reached Dawson, 

 Northwest Territory. There I found dead shells of a Succinea, where 

 a fire had run through the moss, but they were too fragile to handle. 



Snow commenced to fall on September 12th, and that put an end to 

 collecting trips. 



We spent ihe winter on one of the claims on Bonanza creek, in the 

 ordinary occupation of a miner in that latitude, which would be 

 another story. 



After the clean-up in the spring we rebuilt our canvas boat in the 

 shape of a scow to godown the Yukon river 1,800 miles to St. Michael's. 

 We left Dawson on June the 9th and leisurely floated with the current, 

 enjoying the days twenty four hours long; that is, at Fort Yukon the 

 sun was visible all the time. As I heard one man ask another " the 

 time of day," "Eight o'clock" was the answer. The first said: ''I am 

 worse off than before: I do not know whether it is night or morning;."

I did not find any live shells on the upper river, but on the bars found 

 a few dead shells of Succini'a chrysis West. 



The mosquitoes were very bad on the lower river, and it was 

 nearly suicidal to go into the brush; but when about twenty miles 

 below Andreafsky we were compelled to lay over on account of wind 

 and rain. I tried the experiment of building a smudge in the gold- 

 pan and carrying it with me. I was rewarded by finding that the 

 ground and stalks of grass were alive with Succinea chrysis West., and 

 before the day was done I had nearly a pint cup of them cleaned.
