After dinner we crossed the stream, stopped a few minutes
at our hut and then crossed the hills in the direction of the
Observatory.  On the hillside we passed a second stone similar
to the one observed in the morning only marked P. No. 3.  This,
too, was first seen to-day.  Our view from the Observatory was,
as it is always, good.   From the Observatory we went down to
Orange Grove, then kept along the tracks to Relay, where we
took the 6.13 P.M. train.  We reached Balto about 6.30 P.M.
and I was home a little before 7 o'clock.

Jan. 19. 1901.  During the past week, we had several very warm
spring-like days, the thermometer one day reading 64°.  But on Friday [yesterday]
there came a change and the thermometer went quite low.  To-day, I 
think it went still lower, although the Weather Bureau reports higher 
temperature.*   We met again, as last Saturday, at the Catonsville
terminus, at 9 A.M.  About half past seven, just a short time 
before leaving home, we had quite a snow-storm.  It lasted about
15 min. but in that short time, the ground was completely
covered.  Before 8 o'clock the sun was out.  The wind
was blowing furiously, coming in strong and frequent gusts
which carried snow and dirt, hurling <s>them</s> both into the faces
