ROMAN REMAINS AT LEICESTER, ENGLAND.
Some time ago we published the fact that the Empress of Germany
had offered a prize of $1,000 and the decoration of the Order of
the Red Cross to the successful inventor of the best portable field
hospital. Wm. M. Ducker, of No. 42 Fulton St., Brooklyn, sent in a
design for competition. A few days ago Mr. Ducker received notice
that his invention had won the prize. Another instance of the
recognition of American genius abroad.
THE BARBARA UTTMANN STATUE AT ANNABERG, SAXONY.
A Boston paper tells of a man who built two houses side by side,
one for himself and one to sell. In the house sold he had placed a
furnace against the party wall of the cellar, and from its hot air
chamber he had constructed flues to heat his own domicile. The
owner of the other house found it very hard to keep his own house
warm, and was astounded at the amount of coal it took to render his
family comfortable, while the "other fellow" kept himself warm at
his neighbor's expense nearly a whole winter before the trick was
discovered.

Prof. W.O. Atwater, as the results of a series of experiments,
finds, contrary to the general opinion of chemists, that plants
assimilate nitrogen from the atmosphere. They take up the greatest
quantity when supplied with abundant nourishment from the soil.
Well fed plants acquired fully one-half their total nitrogen from
the air. It seems probable that the free nitrogen of the air is in
some way assimilated by the plants.
