is about twenty feet,
and the admirable contrivances of revolving balls (adopted in the
steam-engine) are affixed, to render the power uniform, by varying the
depth of the falling stream. In truth, it is one of the features of the
entire establishment, that all, that can be performed by machinery, is so
performed, and that the machinery is the very best for its purpose, and
in many instances which I witnessed, as true, as decided in its action.

After the thread is wound into hanks, it is bleached at a distinct
manufactory for that purpose; but as bleaching is a mere chemical
operation, and the means are either known and not curious, or secret, and
not proper to inquire about, I did not visit this branch of the
establishment.

The first of the works on this spot, was built by Mr. Jedediah Strutt,
father of the brothers, William, George, and Joseph, about fifty years
since. Arkwright invented the spinning machines, while a barber's
apprentice. He was joined by one Need, and they expended L14,000. with
uncertain success. Wright, the banker, of Nottingham, hesitated to make
further advances, and, at this juncture, they were joined by Mr. Jedediah
Strutt, a careful man, with the necessary credit or capital, and the
result was, the realization of princely fortunes, and the enriching even
the nation itself. On the expiration of their partnership, Arkwright went
on by himself at Cromford, and the Strutts for themselves at Belper. A
spirit of detraction would make it appear that Arkwright stole the
invention of another, but Mr. William Strutt, who knew him well, and is a
competent judge on such subjects, assured me that Arkwright was a man of
very superior talents as a mechanic, and quite equal to such an
invention. I saw two portraits of him in Mr. Strutt's house, and no
higher proof could be given of his personal respect for Arkwright, while
he never failed to speak of him with enthusiasm, as a man of original
talents.

_Derby Silk Trade_.

Silk throwing is a considerable trade in Derby. Sir Thomas Lombe's famous
machinery has not, however, been used for some years, but improved
machinery, which performs twice the work, in less room, is now adopted.
The chief throwsters are Messrs. Bridget, Taylor, Adcock, Butterworth,
Moore and Gibson, Devenport and Forster. The silks, as imported, chiefly
from Bengal and China, are in what are called books of 10 lb. of which
ten form a bale, and the business of the throwster is to wind
