ever and was free from insect or fungus injury. The dry forms of arsenate 

 of lead proved to be as satisfactory as a paste of arsenate of lead when used in 

 solution with lime-sulphur. Soluble sulphur preparations, in which there ap- 

 pears to be no lime, caused the most injury to foliage and fruit. Some injury 

 was also caused by Pyrox and Bordeaux, Taking the results of the two seasons 

 as a whole, lime-sulphur and lead arsenate mixture was more successful in 

 controlling fungus troubles and insects than either Bordeaux-lead arsenate mix- 

 ture or Pyrox.

 thinning each tree is given.
