In August, 1827, the small rivulet called the College, at the foot of the Cheviot Hills, was so swollen by the heavy rains, that the current tore away from the abutment of a mill dam, a large block of stone, weighing nearly two tons, and transported it to the distance of a quarter of a mile.
Cement.
The large snails which are found in gardens and woods, discharge a whitish substance, with a slimy and gelatinous appearance, which has been known to cement two pieces of flint so strongly as to bear dashing on a pavement without the junction being disturbed, although the flint broke into fragments by fresh fractures.
Artificial Ice.
A mixture of four ounces of nitrate of ammonia, four ounces of subcarbonate of soda, and four ounces of water, in a tin pail, has been found to produce ten ounces of ice in three hours.—Brande's Journal.
