fifty percent of the beginners make this mistake and the error 

 must be rectified later at an additional unnecerrary expense. 

 Another eommon error in the purchasing of spraying apparatus 

 is to buy insufficient lengths of hose. For ordinary tree 

 spraying the lines should be at least thirty feet long and 

 for large trees 40 feet lengths are better. At least patria! blame 

 for this fault may be attached to the manufactures of spra- 

 ying apparatus as most ilústrate in their catalogues from ten 

 to fifteen foot lengths. 



Many of the spraying mixtures are eaustic and most are 

 disagreeable if they fall upon one's person, therefore it is ad- 

 visable to wear a waterproof garment when spraying. The 

 long gummed cloth "slickers" are very satisfaetory for this pur- 

 pose. The horses that draw the sprayer should be covered 

 also. 



The following remarks eoneerning the applieation of sprays 

 are taken from the author's paper entitled "Spraying" from 

 the report for 1908 of The Cuban National Horticultura! So- 

 ciety: — ' ' Thoroughness should be an inseparable companion to 

 spraying. It is not economy to half way spray. [nvariably 

 the results are not what they shold be. Better take half the 

 área and treat it thoroughly than the whole and partially do 

 the work. A few antreated twigs upon a tree infested with some 

 scales serve as a veritable pest house to the remaineder of the 

 plant. Tn oder to make the .work thorough, a regular system of 

 procedure should be followed. If a bed is to be sprayed, com- 

 mence at one side and complete each section before leaving for 

 the next. The system that has appealed to the writer as most 

 convenient for spraying trees. is as follows: — If the wind is 

 favorable — that is, blowing from the operator to the tree com- 

 mence at the top of the tree and direct the nozzle from side to 

 side, slowly working downward, until the bottom of the tree 

 is reached. If the wind is adverse, tiras making it necessary to 

 follow up the windward side of each limb ; then begin at the 

 base of the tree and carefully spray the first branch that leaves 

 the trunk; come back to the trunk and take the next branch, etc. 

 until the top of the tree is reached. If such a procedure is 

 carefully carried out, it is comparatively easy to make the treat-
