over the unsprayed. It may be advisable to use the Bordeaux 
mixture in connection with London purple or Paris green when 
either of the latter are used for the potato beetle, as it has been

The conclusion is also reached by the results obtained in Table 
No. 1 and by other spraying experiments, that the Bordeaux mix- 
ture has given better results this season than the ammoniacal 
solution.
