14'2 Inrlian Museum Notes. [Yol. IL 



This is a point that should be borne in mind in the use of iron or galvanised iron 

 pumps or apparatus. These should be carefully washed out before being put away, or 

 the bottoms may be corroded away by chemical action. 



The above observations refer solely to the use of Paris or Emerald-green as an 

 application — 5tJMjo?_y mixed with water for destruction of moth caterpillars in the 

 way in which we have found by many years' experience in America, and now by our 

 own here, that with proper regard to directions and cautions, the work may be car- 

 ried on with safety and great benefit." 



In a note, dated 21st April 1891, Miss Ormerod adds :— 

 At present the number of kinds of * sprayers,' or the improvement in details 

 goes on so fast that in my reports I can hardly keep up with the advance. We now 

 find that Mr. Scott's nozzle answers most excellently, and with this and an ordinary 

 garden engine (small barrel with two wheels) we can send a most beautiful spray to the 

 top of any plum-tree. ........... 



Messrs. Blundell, Spence & Co., ot Hull, are issuing Paris-green damped in bottles* 

 This is an immense improvement, for it cannot fly, be the mixers as unhandy as they 

 please. Also, the powder being ground, extra fine does not settle as much as 

 ander ordinary circumstances."
