cloud, even in those numerous cases in which the vortex or whirl-

13. Perhaps we have also, in these noises, a clue to the sounds 

 which are ascribed to certain moving sands, in the heat of sum- 

 mer, as in the case of Jehel Narkous, or the sounding mountain, 

 near Tor, on the Red Sea,* and also in the Reg-ruwan, on a hill- 

 side, near Cabul, which is described by the Emperor Baber and 

 by Capt. Burnes. From the descriptions given of the localities 

 and the other circumstances which attend these sounds, which, 

 however, cannot be here recited, I have been led to infer that they 

 proceed from the action of a whirlwind formed on the leeward 

 side of the hill, and revolving upon a horizontal axis ; analogous 

 in a degree, as I suppose, to the celebrated Helm Wind of the 

 Cross Fell mountain in Cumberland, (England.) 



The inquiry opened to us by the consideration of these phenom- 

 ena is extensive and interesting, in all its bearings, and I cannot 

 but regret my inability to pursue it with the attention which it 

 so well merits.

To the Editor of the Nautical Magazine. 



Sir — In my account of the tyfoon of August 5-6, 1835, in the 

 China sea, is a paragraph derived from the Canton Register, in 

 which it is stated, that " the American ship Levant, Capt. Dii- 

 maresq, which arrived on the 7th, the day after the gale, came in 

 with royals set, from Caspar Island in fourteen days, having had 

 light winds all the way up the China sea, and did not feel the 

 tyfoon. "t The prolonged absence of Capt. Dumaresq from this 

 country, alone prevented me from verifying this statement. He 

 has now returned and has kindly placed his private journal in my 

 hands, from which I extract the following ; which shows, that 

 in running into the path of the tyfoon from its southern side, the
