upon them would be extremely small in proportion, and regelation would
often occur, and of the immense number of the needles of ice formed at
the surface enough would adhere to produce the effect which we observe
and call anchor ice. The adherence of the ice to the bed of the stream
or other objects is always downstream from the place where they are
formed; in large streams it is frequently many miles below; a large
part of them do not become fixed, but as they come in contact with each
other, regelate and form spongy masses, often of considerable size,
which drift along with the current, and are often troublesome
impediments to the use of water power.

Water powers supplied directly from ponds or rivers, or canals frozen
over for along distance immediately above the places from which the
water is drawn, are not usually troubled with anchor ice, which, as I
have stated, requires open water, upstream, for its formation.

A PAIR OF COTTAGES.


This drawing has been admitted into the Exhibition of the Royal Academy
this year. The cottages are of red brick, tiled roof, white woodwork, as
usual, rough-cast in the gables; but they are not built yet. Design of
