right, and vice verfa , according to the direction in which the wheel is revolved 
(eafily accounted for). The canopy, a dead flat, gave indifferent results at any 
angle and in all pofitions. A hood or bonnet 32" long x -\ 
24" wide gave better refults and a maximum of effed when """-A-?£—A 
1 of the 32" was forward of the plane of revolution, and § to the rear. I alfo 
meafured the angle carefully, having Fred” (the afliftant) “get an independent 
verification thereof, and found it to be inclined above the horizon 34 0 (angle of 
fcreen to the fhaft 34 0 ), and the back end of fcreen 4" below centre of fhaft. 
At the 10th turn of the crank the fcreen will rife 4" to 5" (at back end), and 
remain there fteadily during the run. 
“All the lifting power we have yet been able to attain is to 3 oz.: current 
ading on this large curved fcreen. As to the power , I fend famples of the cords ; 
the fmalleft of the three held well until fomewhat worn.

P.S.—My friend Willis Gaylord, Efq. (of Brooklyn, U.S.A.) has charged 
himfelf with the duty of “ materializing ” fome of the ideas fet forth in the pages 
of this book— patents being one of the “ conditions.” 
So far as Water navigation i$ concerned, I am reconciled to this; but not 
as to the Air. If the theory of “ Paflive locomotion ” herein fet forth be the 
bafis needed by inventors, in order that mankind may realize their long-cherifhed 
dreams, that bafis fhould be free to all: more efpecially in view of the unufual 
incidents attending its promulgation to the world. Under thefe circumftances 
I defire to have it underftood by all inventors, that, fo far as regards the new 
principle of aerial navigation fet forth in thefe pages—and the “ fanning-wheel ” 
defcribed herein as a “ redudion to pradice ” of the new principle—they are to 
be regarded as the common property , and as being hereby dedicated to the Jervice of 
all mankind.
