"A negro farmer in Dougherty coun-
ty, Ca, has succeeded in making ex-
csllent sirup from watcrmelons, and
thus a new use is devised for the sur
plus crop.
Hard wood cut in June, July or
August, and left untrimmed until the
leaves have drawn the sap from the
trees, makes the most solid and lasting
timber.
Among the recent mechanical in
ventions is nail machine which cuts
either a wire or cut nail with equal
facility. The construction OF this APP
paratus is quite simple, as compared
with ordinary wire nail machines.
With it, cut nails of square section,
with either diamond or chisel point,
may be produced as easily as the COM
| mon nail, and the change from wire to
cut nails may be accomplished in a few
minutes.
| Extended observations at Paris
and at Munich indicate that the sani-
tary condition of a locality depends on
| the amount of water contained in the
ground. The years in which there has
been large quantity of ground-water
present have invariably been the
healthiest years, while those in which
there has been smaller quantity have
invariably been the unhealthiest pc
riods.
The Lancet defines the disease
which is known as 1.-The Sightseer
Headachen as natures tax levied
on the comfort of that great body o.
busy idlers to which we all at some
time or other belong. 1t is endemic
among the frequenters of museums
picture galleries, and exhibitions, vary
Ing somewhat perhaps in different
cases in its precise causation, but asso
ciated always in manner significan
of its origin with the habits OF the oh
servant loiterer."
1t is claimed to be proven, beyon
all doubt, that waters which circulat
orstand in leaden pipes or vessels, no

mechanical action due to friction, bl

being generally lead carbonate. A.

n Some remarkable changes ha
he recently been noted by nj. Perrotin
Ky the planet Mars. In letter to
D. Academic des Sciences, he reports Il
of the tract of land on both sides OF
tn equator, which has been named Lyt
Id seems to have been submerged by
to sea. 1t was distinctly seen by him
IN years ago, when it was bounded on
ce sides by sea. and on the others by
TX, of the streaks to which M. Schiapar
m gave the name of canals, but now d
re- not exist. A drawing made by him
on 1882 shows the same appearance, wh
is leads him to the conclusion that the
undation, if it be such, is periodic.
