 He said he used one pound of Paris green to 125 gallons of 

 water. The cattle should of course be kept away from the 

 grass beneath the trees. Great care is necessary to prevent 

 injury to the foliage by the Paris green. 



Mr. Ware said a pound of Paris green to 80 or 100 gallons of

 When feeding on the leaves it may be safe to shower with Paris
