longitudinally ; but the proportion of such contraction is very 
small, as compared with the shrinking in bulk. With regard 
to the cost of the wire, I believe it may be safely estimated at 
Is. an acre, and something may be calculated for the old wire, 
which could be worked up again. I have previously stated that 
in all the automatic binders the form of the machine was similar 
to the ordinary harvester. The following figure, which repre- 
sents a plan of W. A. Wood's Harvester and Self-binder com- 
bined, will, with the lettered description, give a good general 
idea of the apparatus and the modus operandi.
