April 11, 1902.  Arbor Day.  The first trip with my botany class.
We met at 2:30 P.M. on the Edmonson Av. Bridge.  We walked
along the west side of the falls to Walbrook.  There were about 20
in the party.  The day was partly cloudy and towards the close of our
trip we were threatened with a shower.  We, however, felt only a few
drops of rain.  We were pleased to find Erythronium in bloom.  Lithospermum
arvense, Viola cucullata, Ranunculus arbortivus, Stellaria pubera, Vinca minor, Luzula campestris,
Poa brevifolia and Dentaria heterophylla were found for the first
time, this year.  Saxifraga Virginiensis was found so plentifully
that we decided to call the day Saxifrage Day.  I had hoped
that Dirca would be found in full bloom, but a few blossoms
only were found open.  This no doubt is due to the cold rather
unsettled weather for the past 10 days.  <s>The</s> Its buds seem to
be at a standstill.  The Elms[note at top of page: Ulmus Americana; Ulmus fulva is still found in bloom.]  are now in fruit, instead of
being clothed in brown as they were two weeks ago they have
now a silvery lustre.  The Red Maple is still in bloom.
The Willows alone are putting forth green leaves.  In the city
however, the European Linden seems foremost, perhaps this, however 
is only apparent as its leaves are so decidedly green, those of 
the Silver Maple being of a reddish brown color.
