Machine for heating out Hemp seed, 469 
Vould do as much as fifty or sixty could do in the old way, and with 
much more ease and pleasure to themselves ; and this is not the on* 
ly advantage that would result from such mills; it would cause 
something of a social meeting, which the youth would be particu- 
larly fond of. At such meetings all the defects respecting the cul- 
ture and management of hemp would be examined into, and those 
who raised the best would become ambitious, and try to excel each 
other ; thus we might reasonably expect, that Upper Canada would 
far exceed all other countries in the world for the growth of good 
hemp. 
"Reference to the Engraving of Mr. Bond's Machine for breaking 
Hemp. Plate . Fig. 3, 4, 5. 
Fig. 3- a represents the axis of a water wheel, on which is 
fixed a trunnion of four lifters b b b b, each of which lifters raises 
in succession a lever c, which, by means of a chain connected with 
it, pulls down another lever £/, and thereby raises the upper part 
Of thd double brake e. As each lifter of the trunnion passes the 
lever c, it allows the upper part of the brake to fall upon the hemp 
placed on the lower part of the brake f f ; and by its weight, and 
^eeth intersecting the teeth of the lower brake f /, the woody parts 
of the hemp plant are separated by repeated strokes from the fila- 
ments or fibres of the hemp proper for use. This completes the 
first operation necessary in the preparation of hemp, g is a table 
on which the woody parts of the hemp fall, and which gives secu- 
rity and strength to the frame ; hhhh are the four legs or supports 
i of the frame. 
Fig. 4. shows a section of the teeth of one half of the double 
brake above mentioned : it is betwixt the upper and lower rows 
of these teeth that the breaking of the hemp takes place, by the re- 
peated rise and fall of the upper part of the brake upon it. 
Fig. 5. shows the upper part of the brake, in which it shows 
the two rows of teeth, k k the two pins on which it is moved, /the 
part to which the chain which raises the upper part of the brake is 
attached. After the breaking of the hemp, it is wholly finished for 
use by scutching or swingling, an operation which may be either 
performed by the hand or machinery, and is easily executed by ei- 
ther mode. 
The machinery for breaking hemp should be removed from fchQ 
rivers previous to the beginning of the frosts.
