S9. Blowing Sand.-^On 20th March 1821, in N. Lat. 
11° S', W. Long. 22° 5', it was observed by a gentleman going 
to the East Indies (Mr James Alexander, a cadet), that sand 
in considerable quantities was found adhering to the upper 
rigging of the ship. This must have been blown from the shores 
of Africa, the nearest point of which was at least SOO miles 
distant from the ship. — Extracted from Mr Alexander’s Journal

SO. Account of the Stupendous Cavern of Watertown.^ThQve 
was discovered, about three weeks since, on the north bank of 
the Black River, upon the land of Jam^s le Ray, Esq. opposite 
to the village of Watertown, an extraordinary cavern or grotto, 
the mouth of which is about ten rods from the river, north of 
the Falls of Cowan’s Island. 
The great extent of the cavern, and the great number of spa- 
cious rooms, halls, and chambers, into which it is divided, and 
the immense quantities of calcareous concretions which it contains, 
and the different states of those concretions, from the consistence 
of lime-mortar to that of the most beautiful stalactites, as hard 
as marble, fender it difficult, if not impossible to describe it ; and 
I shall only attempt to give a faint description of three or four 
rooms. 
The mouth of the cavern is in a small hollow, about 5 feet 
below the surrounding surface of the earth. You then descend 
16 feet and a half, into a room about 16 by 20 feet, and 8 feet 
high, and behold in front of you a large flat or table rock, 12 
or 14 feet square, 2 feet thick, and elevated about 4 feet from 
the bottom of the cavern, the roof overhead covered with stalac- 
tites, some of which reach to the table rock. On the left hand 
is an arched way of 100 feet and 50 feet ; and, on the right hand, 
is another way, 6 feet broad at the bottom, and 6 feet high, which 
leads into a large room. Passing by this arch about 20 feet, you 
arrive at another, which leads into a hall 10 feet wide, and 100 
feet long, from 5 to 8 feet high, supported with pillars and ar-
