_Notes_.--The time of my visit was most unfavorable. The best time is
when the morning has just dawned and the dew is on the grass. One then
can find an abundance, while after the sun is up and the air is hot the
plants disappear; probably burst and scatter the spores in billions,
which, as night comes on and passes, develop into the mature plants,
when they may be found in vast numbers. It would seem from this that the
life epoch of a gemiasma is one day under such circumstances, but I have
known them to be present for weeks under a cover on a slide, when the
slide was surrounded with a bandage wet with water, or kept in a culture
box. The plants may be cultivated any time in a glass with a water
joint. A, Goblet inverted over a saucer; B, filled with water; C, D,
specimen of earth with ague plants.

Observation 6. Some Gemiasma verdaus; good specimens, but scanty.
Innumerable mobile spores. Dried.

Observation 7. Red dust on gray soil. Innumerable mobile spores. Dried
red sporangia of G. rubra.

Observation 8. White incrustation. Innumerable mobile spores. No plants.

Observation 9. White incrustation. Many minute algae, but two sporangia
of a pale pink color; another variety of color of gemiasma. Innumerable
mobile spores.

Observation 10. Gemiasma verdans and G. rubra in small quantities.
Innumerable mobile spores.

Observation 11. Specimen taken from under the shade of short marsh
