obieftors, “ If you leave your hold it will recede from you.” 
My prescription would be “ Keep it well shaken.” But al- 
though I have advanced this illustration ot the carpet, the 
cases are not exa<5Uy parallel. By the peculiar vibration 
given to my arrangement a double wave-aCtion is imparted, 
-—that is, along the wing-arms, and obliquely throughout 
the fabric from front to back, — so that the air is propelled 
laterally, the fabric being attached to the body or shatt 
which runs down the centre like the back-bone of a kite. 
For all answer the propelling power of such an arrange- 
ment has been proved to be effective. The sustaining pro- 
perty is not disputed. Moreover, owing to the bellying 
of a large surface, from the great resistance offered by the 
air, a gradual and safe descent is ensured in the direction of 
advance, upon cessation of the motive power. 
This is my “ Flighty Aspiration,” irrespective of details, 
and I contemplate its construction.
