This apparatus is now in operation in the different stations that the
Versailles waterworks has established near the reservoirs of the plateau
of Trappes, and it is also installed in several primary normal schools,
where it is giving very good results.--_La Nature_.

CHARRED CLOVER.


A correspondent of the _Ohio Farmer_ reports an experiment in curing
clover, showing how he just missed breeding fire in his barn, and
illustrating the importance of ventilating hay mows:

In 1861 I used a horse fork for the first time. The haying season was
not a bright one, and our clover was drawn a little greener than usual,
and went into the mow in large and compact forkfuls. The result was
intense heating, and consequently very rapid evaporation and sweating of
the mow. On a bay holding ordinarily twenty tons we put at least thirty
tons, as every load at the top seemed to make room for another. The barn
was rather open, which allowed quite free evaporation on all sides as
well as at the top. The result was that I had very bright and excellent
hay at the bottom, top, and sides of that mow, but severals tons in the
center were as completely charred as though burned in a coal pit. What
prevented combustion has always been a mystery to me. Since that escape
