110 THE NAUTILUS. 
well paid for the time spent. I also found Pyramidula striatella 
cronkhitei Newe. and Conulus fulvus 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 sincera Say and 
Linnea palustris Mull. 
The next day we put together our canvas boat, made of twenty- 
ounce duck, ready for our 600 miles trip down the Lewes and Yukon 
rivers to Dawson. At Marsh lake found dead shells of L/niiea ampla 
Migh., some very large, one measuring one inch aud a half long and 
one inch across, and a dwarf variety of Limnea palustris Mull. 
The only shell collected going down the Lewes river was Succinea 
nuttalliana Lea. 
We ran the famous Miles cafion 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 Suceinea, 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 the 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,” “ Kight o’clock’’ was the answer. The first said: ‘Tam 
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 Succinea 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.
