160 Rhodora [JUNE 
A wet slope between two of the cliffs gave us Castilleia pallida, var. 
septentrionalis, Juniperus communis, var. nana, Carex atrata, var. ovata, 
Avena striata, Agropyron violaceum, Cardamine bellidifolia, Potentilla 
Jruticosa and Galium Kamtschaticum. 
Monday, July 16, we broke camp and started upon our return down 
the mountain by the same path. I do not recall that on that day we 
‘had rain before late afternoon, but certainly on the day following, 
when we rode from the Bell Camp to Lunksoos, there came a flood ; 
and we were compelled again to remain in the open wagons rather 
than wade through many pools and swollen brooks, In skirting the 
edge of the ** Depot Pond," and at some other places, we collected 
some notable Carices; and along the gravelly bank of the Wassata- 
quoik we saw much Prunus pumila, quite unlike our Sand Cherry 
of Massachusetts, P. cuneata, with which it has been confused. 
Tuesday night we reached Lunksoos, which now seemed a most 
luxurious abiding place. Thence by way of Stacyville, through fare- 
well torrents of rain, submerged forests and corduroy roads, our lit- 
tle party dispersed, in the diverse directions in which pleasure or 
duty called. 
A COMPARISON OF THE FLORAS OF MT. WASHING- 
TON AND MT. KATAHDIN. 
EMILE F. WILLIAMS. 
Mr. KATAHDIN lies 161 miles northeast of Mt. Washington. 
The latitude of its highest summit, the West Peak, is 45? 53' 40". 
The latitude of Washington is 44° 16’ 25", a difference of 1° 37’ 
15", about 112 miles. The altitude of Mt. Washington is 6300 ft. 
above the sea; the most reliable determination of the altitude of 
the West Peak of Katahdin, made by Prof. M. C. Fernald, gives it 
a height of 5215 ft. above sea level. Both mountains have a simi- 
lar geological formation, almost entirely granitic. 
As might be expected, the general conditions for plant life are 
very similar on these mountains. Both are surrounded by vast 
areas of wooded country, both are abundantly watered by innumer- 
able springs and rivulets, which well up out of the ground at very 
great elevations and both ranges are sufficiently high and extensive
