Experiments upon the Production of Cahots. I proceeded to experiment upon the productionof cahots. Obtaining a large basket which hada form something like a Laplanders sledge, Irepaired to the little beach of sand and shingleon the shore of Coniston Water, near the steam-boat pier. Having weighted my sledge, whichwas not on runners, and should, therefore, haveproduced undulations more quickly, I hauled itabout on the coarse sand and fine shingle ofthe highest portion of the beach, several feet M I 1 ^^H 1 I im 1 1 H 1 1 ^m [Br J^^ V ^^^^^R^Bw ^ ^^^^^B«^^ I^^M Ik 1 E Ig^^^^^^J^^H 1 1 tJO r^ K! o u 13 •y) rt O Q T3 ri m txi a <D ojo O Oh 237.

I then tried the effect of drawing it backwardsand forwards over the same track, thinking thatin this way I might produce some undulation ; thetrack, however, remained flat. I was carefulnot to draw the sledge over my own foot-prints. Friends having come to my assistance, a higherspeed was tried, the sledge being dragged at about8 miles an hour. I thought an undulation mightarise from the tendency of small inequalities tomake a sledge jump when moving rapidly, butin spite of a good deal of hard work the trackof the sledge remained quite flat. I had been trying whether undulations wouldform upon a level surface, because my experiencewith waves of sand and snow had shown me thatthe formation of surface-waves does not requirethe pre-existence of appreciable inequalities.
