and so become a source of danger. They should 
therefore be entirely destroyed—either burnt, or 
deeply buried. In no case should they be used 
as manure, or as food for domestic animals, as 
is often done, for the resting-spores (oospores) 
do not lose their vitality or hurtful pro¬ 
perties. 
By following these instructions, which are 
general, and may readily be applied to a large 
number of vegetable parasites, it will be pos¬ 
sible both to neutralise the centres of infection, 
and to prevent them spreading. The more 
valuable the crop, the more care should be 
given to their application.—M. 
KID GW AY’S HEDGE-CUTTING MACHINE. 
GppT is not always that a new implement 
^ Ip can be honestly described as a decided 
improvement upon those which have 
previously been employed to effect the same 
object, but this new form of Hedge-shears 
will be as great an acquisition for the trim¬ 
ming of hedges, as in its day was the mow¬ 
ing-machine for the cutting of grass-lawns. 
From trials which we have witnessed we arc 
quite convinced that it may be depended on to 
do its work not only easily, but rapidly. 
The character and general appearance of the 
machine will be understood from the accom¬ 
panying w'oodcut, in which, however, the teeth 
of the back knife are not shown as slightly 
serrated, which they are in the implement, so 
as to form a “ bite,” and thus to facilitate the 
cutting process. The top knife only is sharp¬ 
ened when necessary. The machine is held 
and guided to its work by the left hand, the 
right handle being moved to and fro with a 
sharp twitch, causing it to click with every 
upward or downward motion. It can be 
worked with either the right or the left hand 
uppermost, the operator moving along the 
hedge at a slow walking pace. The work done 
is all that can be desired, either as to neatness 
or excellence, compared with the ordinary hedge-
