33. Another larger steam engine and wings. 
34, Some steam jet motors, 
35. The evolution of the cellular kite, A is the first one made, 
it is constructed of drawing paper. J is aluminium. 
36. More evolution. 
38. The four kites I managed to lift myself with. James 
Swaine who helped me. Thereel and line. The bags (filled with 
sand on the beach). The spring balance to read the pull when 
Swaine had let out all the line. The anemometer to read the 
wind velocity. The fishing line to plumb the vertical height. 
The slung seat (better than any basket). The barrow to convey 
the gear down to the beach at Stanwell Park. 
39. Small Laval turbine on a screw. Donkey pump to test 
evaporative power of boiler shown in photograph 40.

horizontal wind. 
52, 53, 54, 55, 56, 57, Other objects that further strengthened

could be found till they were tried as accessories to and economisers 
of power on a propelled aeroplane.
