February 6, 1904.  A trip from Mt. Winans to Lansdowne, along the B. & O.
R.R. then by way of Sulphur Spring <s>Rd</s> and Cannon R'ds to Avalon, then
along River R'd to Ilchester, and to Catonsville by way of Thistle Glen
R'd.  I left home about 8 A.M. and walked along the railroad 
tracks to Mt. W. where I met Mr. W. & Mr. F. about 8:30.

The weather was delightfully spring-like.  The Weather Bureau
had predicted rain for the day, but at the time of meeting the sun was shining.
Later in the day, about noon, it rained a little, hardly
enough, however, to dampen our clothes.  As we passed the little
swamp at the intersection of Washington & Sulphur Sp. R'ds we
stopped a moment to look at the Lygodium.  I found it without
difficulty.  Mr. F. had never seen it before, so was much pleased to see it.
Botrychium ternatum was also found and in the spot near the road
several patches of Symplocarpus foetidus.  Most of the specimens showed
the effects of frost.  One very nice specimen was tested with a thermometer, 
we wished to see if the temperature inside the spathe was warmer
than outside; but the air to-day was unusually warm, and it was actually
colder in the spathe.  Had I found a very nice spathe, I should have noted
the difference in temperature inside the spathe, and outside in the surrounding soil.

It was noon, by the time we reached the old hotel, so we stopped to eat
