520 THE MONTHLY BULLETIN. 



was 13.44 pounds, of late pruned vines. 18.64 pounds. Pruning after 

 the terminal buds had started seemed to increase the crop irrespective 

 of frost injury, the crop on vines pruned ^larch 14, averaging 17.72 

 pounds per vine, and of vines pruned April 14, 22.55 pounds, but 

 pruning after the shoots had grown several inches made a big decrease 

 in yield. Late pruning also delayed the time of ripening, late pruned 

 vines giving grapes with much less sugar at time of harvesting, though 

 the grapes with less .sugar would have ripened up more if left on the 

 vines. Late pruned vines also gave grapes of inferior quality: by late 

 pruning in this case being meant pruning delayed too long. Appar- 

 ently as late pruning as can be done without reducing the yield, that 

 is, when terminal buds are just about to start, is good for the yield 

 and good as a method of running less ri.sk of frost injury. — Orchard

The Los Angeles Convention. — The attendance and interest at the 

 recent State Fruit Growers Convention left little to be desired. I 

 believe such meetings are of lasting benefit. The attendance must of 

 necessity be largely local, l)ut the scattering attendance from all por- 

 tions of the state is so much leaven to spread the valuable truths 

 and suggestions which are so generously offered. 



I have two criticisms to make regarding the program of this con- 

 vention. It was too crowded. I think, after many years of experience, 

 that three papers at a session are quite enough. Also, I believe that 

 one half of the papers or addresses should be from the growers them- 

 selves. It was impossible to meet either of these conditions at Los 

 Angeles, yet we need not lament very greatly for there was time for 

 discussion of each subject, and all the papers were of great value. 



Too much praise can not be accorded to the local committee nor to 

 Dr. Webber and the admirable corps of workers from the Riverside 

 Station for their part in the success of the convention. I wish also 

 to extend very grateful acknowledgements to all who took part in 

 carrying out the program and in the discussion. — A. J. C. 



Citrus Canker.— The Gulf States from Florida to Texas are much 

 concerned because of the appearance of citrus canker in their groves. 

 ]\Ir. E. W. Berger. Inspector of Nursery Stock. University of Florida. 

 Gainesville, in an official tour of inspection in 1912. found the disease 

 in Alabama and ]\Ii.ssissippi. It was already known to exist in Florida 

 and Texas, and ]Mr. Berger thinks it may also be in Louisiana, though 

 a limited inspection failed to di.scover it. It has since been found in 

 Louisiana. 



The supposed nativity of citrus canker is Japan. It is a fungous 

 disease and attacks twigs, leaves and fruit of most, if not all. species 

 of citrus. It blights the twigs, causing numerous slender twigs to 

 push out, reminding us somewhat of peach yellows. It spots the 

 leaves, causing them to turn yellow and to fall prematurely from the 

 trees. Its attack of the fruit resembles scab, for which it has been 

 mistaken. The scarring of the fruit ruins it for market, although not 

 really for eating as the scarring is only skin deep.
