Experiments with the light inclosed in a white globe and running all
night were different in their results. The effect was much less
marked. Lettuce was decidedly better in the light house; radishes were
thrifty but did not produce as much as in the dark house. A third
series of experiments with the naked light running a part of the night
only were also made. Radishes, peas, lettuce, and many flowers were
experimented upon. The lettuce was greatly benefited by the light.
"Three weeks after transplanting (Feb. 5)," we are told, "both
varieties in the lighthouse were fully 50 per cent. in advance of
those in the dark house in size, and the color and other characters of
the plants were fully as good. The plants had received at this time
701/2 hours of electric light. Just a month later the first heads were
sold from the light house, but it was six weeks later when the first
heads were sold from the dark house. In other words, the electric
light plants were two weeks ahead of the others. This gain had been
purchased by 1613/4 hours of electric light, worth at current prices of
street lighting about $7."

This experiment was repeated with the same results. In the second
experiment the plants receiving eighty-four hours of electric light,
costing $3.50, were ready for market ten days before the plants in the
dark house. The influence of the light upon color of flowers was
variable. With tulips the colors of the lighted plants were deeper and
richer than the others, but they faded after four or five days.
Verbenas were injured in every case, being of shorter growth and
losing their flowers sooner than those in the dark house. "Scarlet,
dark red, blue and pink flowers within three feet of the light soon
turned to a grayish white." Chinese primulas seven feet from the light
were unaffected, but those four feet away were changed. Lilac colors
were bleached to pure white when the light struck them fairly. An
elaborate series of tables of the effect of the light is given in the
paper. The author believes it possible that the electric light may be
used some day to pecuniary advantage in floricultural establishments.

These experiments naturally open up many questions. Those which will
be of most importance to the practical man will be such as relate to
the benefits to be derived from the use of the electric light. That
electricity has a great effect upon vegetation can no longer be
denied. What remains now is to ascertai
