with a handkerchief the edge of the cover. Then the capillary attraction
held the cover in place, as is well known. The handkerchief or white
paper was spread on the ground at my feet, and the observation conducted
at once after the collection and on the very habitat. It is possible
thus to conduct observations with the microscope besides in boats on
ponds or sea, and adding a good kerosene light in bed or bunk or on
lounge.

August 11, 1877.--Excursion to College Point, Flushing, Long Island:

Observation 1. 1:50 P.M. Sun excessively hot. Gathered some of the white
incrustation on sand in a marsh west of Long Island Railroad depot.
Found some Gemiasma verdans, G. rubra; the latter were dry and not good
specimens, but the field swarmed with the automobile spores. The full
developed plant is termed sporangia, and seeds are called spores.

Observation 2. Another specimen from same locality, not good; that is,
forms were seen but they were not decisive and characteristic.

Observation 3. Earth from Wallabout, near Naval Hospital, Brooklyn, Rich
in spores (A) with automobile protoplasmic motions, (B) Gemiasma rubra,
(C) G. verdans, very beautiful indeed. Plants very abundant.

Observation 4. Walking up the track east of L. I. R.R. depot, I took an
incrustation near creek; not much found but dirt and moving spores.

Observation 5. Seated on long marsh grass I scraped carefully from the
stalks near the roots of the grass where the plants were protected from
the action of the sunlight and wind. Found a great abundance of mature
Gemiasma verdans very beautiful in appearance.
