ANOTHER GLIDER.

   I enclose a photo of my glider, which I think you might care to put in your valuable paper. It is a biplane, built to my own designs, and of somewhat original shape. Note the boat-like shape of the lower plane; this gives it perfect automatic lateral stability even in a strong wind. I finished it a day before I sailed to South Africa, so was unable to give it a fair trial, but it made a very successful short glide in Wimbledon Park, with a fairly strong side wind. The machine kept a perfectly steady keel throughout, and my model does not object to even a strong wind. The photo, I'm afraid, is a bad one, taken in a rapidly failing light, with a four minutes' exposure. My mechanic is seen silting in it.
   I give a few dimensions : -
Span of main planes ... 22 1/2 ft.
Width of same : 6 1/2 ft.
Length of elevating planes : 13 ft.
Total lifting surface about : 285 sq. ft.
Weight : 150 lbs.
   The whole frame is constructed of ash, except the elevating planes, which are of bamboo. It is mounted on strong bike wheels.
   Patents are being taken out for this invention.
