THE MALAY KITE.
Experiments have been made. too. with kites
built on the model OF birds. A form which seems TO
have with some success Is what Is known as
the Malay kite. William A. Eddy. OF Bayonne, ~
j.. has invented which. although In general
shape similar to the kites flown by boys, differs In
the important feature that the crosspiecs is bent
backward and fastened by string attached 70 the
end The cord Is adjusted the 1uncture Of these
crosspieces and the surface-not the concave

same general principles the Eddy kite, instead

1t is thought that these two forms will form basis
upon which logical experiments may be conducted.
The cellular kite is the first ever constructed
In this country. and is. indeed. by Its stability and
good behavior. a curiosity when ITS peculiar appear

made far with kites OF Japanese or Chinese ori-
gin. but they have been destroyed one after another
as being UNFIT for the purposes OF science. In the

on this work believes that kite can be made which

Elaborate observations taken by Clayton. the

altitude Of eight or nine miles. The promoters OF

PROFESSOR MOORE'S FLYING TOP
instrument which Professor Moore has in
mind for his experiments suggested to him on
a recent visit TO Chicago. when he noticed a new
style or nying top, which the fakirs were selling In
the streets A string pulled quickly. and a
rapidly revolving propeller blade forced the light
affair up In the air with the speed OF sky rocket.
The new instrument will be built this principle.
1t will consist OF cylinder having a conica roof
with projecting inside OF the cylinder will
be an electric motor which Will provide the power
for the propeller located az the base OF the cylinder
The cord which will control this device will also
be the wire TO carry the current. When the desired
height Is reached a parachute attachment will be
unfurled and the machine will be kept at the de-
sired elevation. Inside the cylinder will be a
hygrometer. aneroid barometer. and a thermo-
graph Free passage of air will be allowed through
this cylinder from the bottom. which will be per-
fOrated. and under the projecting caves. where
there will be ventllating holes The working out OF
the details has been assigned to Professor Marvin,
the designer OF many Of the most valued and useful
OF the Weather Bureau Instruments, and the man
