are being supplied care must be exercised to see that the 

 pumper does not take his work too easily. The barrel 

 outfit may be carried through the orchard in any kind of 

 a one-horse wagon or on a drag. The driver does the 

 pumping while a man is needed on the ground for each 

 line of hose. 



A thoroughly good outfit such as has been described 

 will cost about $25.00 and with proper care it should last 

 for a number of years. It will serve equally well in the 

 application of all arsenical poisons for leaf and fruit feed- 

 ing insects or for those attacking many of the garden or 

 field crops. It may also be used for whitewashing. Al- 

 together such an outfit is one of the most profitable pieces 

 of equipment that any orchardist can own. Its intelli- 

 gent use will go farther toward the production of profits 

 with almost any crop than can any equal expenditure 

 made in other ways without the spraying. 



Information regarding "power sprayers" may be had 

 from the catalogs of manufacturers and suggestions re- 

 garding them will be gladly given anyone upon applica- 

 tion to the Entomologist, Alabama Experiment Station,

Spraying Suggestions. — While much in regard to 

 spraying can be learned only from experience, there are 

 many suggestions that may be of aid to the beginner. 



Only the most careful work is worth doing at all. Care 

 should be taken to cover the twigs and small branches as 

 thoroughly as the larger branches and trunks. If the tree 

 is completely dormant, heavy drenching with the wash 

 will not injure it and it is better to use more spray than 

 is really needed than to use too little to 5.o the work thor- 

 oughly. Do not undertake to spray when the prospects 

 are for an immediate storm or severe cold spell since if 

 these should occur before the wash has dried thoroughly 

 on the trees the work will have to be repeated to be effec- 

 tive. Good work cannot be done when a strong wind is 

 blowing. Select fair, calm weather for the work when- 

 ever possible or else make a second treatment when it is
