must use and the grades of flour it must make, and have him make a
programme for the mill and plan the machinery to fit it. Then have the
mill built to fit the machinery. When it starts follow the programme,
whether it agrees with your preconceived notions or not, and the mill
will, in ninety-nine cases out of one hundred, do good work.

MACHINE FOR DOTTING TULLES AND OTHER LIGHT FABRICS.

Dotted or chenilled tulles are fabrics extensively used in the toilet
of ladies, and the ornamentation of which has hitherto been done by
the application to the tissue, by hand, either of chenille or of small
circles previously cut out of velvet. This work, which naturally takes
considerable time, greatly increases the cost price of the article.

A few trials at doing the work mechanically have been made, but without
any practical outcome. The workwomen who do the dotting are paid at
Lyons at the rate of 80 centimes per 100 dots; so that if we take
tulle with dots counter-simpled 0.04 of an inch, which is the smallest
quincunx used, and suppose that the tissue is 31 inches wide and that
the daily maximum production is one yard, we find that 400 dots at 80
centimes per 100 = 3 francs and 20 centimes (about 63 cents), the cost
of dotting per yard. It is true that the workwoman furnishes the velvet
herself.

Mr. C. Ricanet, of Lyons, has recently invented a machine with which he
effects mechanically the different operations of dotting, not only on
tulles but also upon gauzes or any other light tissues whatever, such
