tion was found to be considerably more advanced than at the 
head of Lindeman owing doubtless to the somewhat smaller 
snowfall and the dryer, more sandy soil. A lupine, one or 
two violets and a species of /tzbes were in full bloom, Aguzse- 
tum arvense was in good fruit and a young fern had reached 
a height of 5 or 6 inches on June 2d. But little collecting 
was done here owing to lack of time and as no more stops of 
any length were made from this place on to Dawson, a dis- 
tance of 525 miles, but little collecting was really done along 
the Yukon. At Dawson I remained from the 21st of June, 
1898, to the 14th of Aug., 1899, and doubtless a fairly com- 
plete collection of the higher plants, mosses and lichens was 
made, growing within 2 or 3 miles of town. All the moun- 
tains near Dawson are low (1,200 or 1,500 feet above town, 
which has an elevation of some 1,700 feet, I believe) and 
without snow for 3 months during the warm season. Rains 
were not very frequent or heavy during the summer spent 
there and snow fell in winter about 16 inches deep in town 
and perhaps twice that amount on the mountains near. 
Aug. 14, 1899, I left Dawson, coming out by the same 
route as that traversed going in till the head of Lake Bennett 
was reached on the 25th. Frequent stops along the Yukon 
allowed the collection of some flowering plants at this season 
as did a stop over night at Bennett City. On the 26th I took 
the train at this place for Skagway. We started at 7.15 
A. M., reached the White Pass Summit (elevation 2,600 feet) 
at 9.25 A. M. where a stop-over of 1144 hours gave time to ob- 
tain a number of specimens just on the line between Alaska 
and British soil, then we continued on down to Skagway 
arriving there early in the afternoon where the last collecting 
of the trip was done while awaiting a steamer for Seattle.
