it found that a dose of poison had been inchided in its first menu. 

 We had thoroughly drenched ever}^ bud with a strong Paris 

 green mixture ; the buds will stand the poison at the rate of one 

 pound in 50 to 75 gallons of water, providing an equal amount of 

 freshly-slacked lime is also added. Literally paint the buds with 

 this mixture, and renew the application in a few days, or sooner 

 if rains occur. Anj^ of the other similar arsenical mixtures, like 

 London purple, Kedzie's white arsenic mixture, arsenate of lead, 

 or green arsenite will doubtless prove equally as effectual as 

 Paris green. The measure of success of this method will depend 

 entirely on the thoroughness with which it is carried out. We 

 saved the grape buds the season we tried this spray. The method 

 is practicable and our experience demonstrates to us that it can 

 be made a paying success. 



It is thus possible and practicable to successfully combat the 

 pest earl}^ in the spring before it can do much damage on the 

 buds. It is only necessary to exercise a little watchfulness and 

 be on hand with your kerosene pan or sheet, or your poison 

 spray, the moment the advance guard of the beetles are seen on 

 the buds. Of course, one should always endeavor to check the 

 pest thus early in the season before it ruins the prospective crop 

 of fruit. But oftentimes it happens that the grape-grower 

 awakens to his danger too late ; perhaps he did not realize that 

 the pest w^as in his midst or he may not understand its habits and 

 life-history. Can he do anything that season to prevent a like 

 destruction of his grape buds the next spring ? This is the query 

 we are usualh* called upon to answer whenever our attention is 

 called to this pest. 



Yes, grape-growers can strike a ver}^ effective blow at the 

 insect later in the season after the beetles which ate the buds in 

 the spring have practically disappeared. First, the grape-grower 

 must learn to recognize the little brown grubs or larvae of this 

 flea-beetle, so that he may know w^hat he is to fight. Those 

 fruit-growers who understand what they are spraying for get 

 much more satisfactory results than those who spray simply 

 because their neighbors do. 



It should be a very easy matter for the grape-grower to make 

 himself familiar with the grubs of this grape-vine flea-beetle
