 and unpruned Marsh grapefruit trees. California Citrograph 5: 248, 268. 4 fid- 1920. — 

 Experiments showed that heavy pruning of middle-aged vigorous grapefruit trees reduced 

 the crop with no compensating benefits. The author recommends the training of young 

 trees to proper form; the renewal by heavy pruning of old worn out trees; and the pruning 

 out of dead brush and conflicting branches at any time. Aside from this he would not prune 

 Marsh grapefruit trees. — J. E. Coit.

 Agric. and Stock Dept. Rept. 1918-19: 19-20. 1919. — Brief notes on the following: a fruit 

 tree disease, caused by Armillaria mellea, can be prevented in early stages by cutting away 

 all diseased tissue and painting over the wound with Bordeaux paste; a treatment of apples 

 with nitrate-caustic soda spray did not have appreciable effect on fruit production or growth. 

 Experiments are in progress with stocks for fruit trees, cold storage of fruit, etc. — D. Reddick.

1780. Truelle, A. La vente des pommes de calville blanc, de Meran (Tyrol). [Marketing 

 white Calville apples from Meran (Tyrol).] Rev. Hortic. 91: 378-380. Nov., 1919.— Special 

 methods of grading and packing are followed in marketing the fruit in order to utilize it to 

 the best advantage and to derive the largest profits from its sale. The fruits are first graded 

 into three classes. Class A contains perfect fruits only; Class B those which have slight de- 

 fects; and Class C those which have more pronounced imperfections. These groups are 

 again divided according to the form, beauty, and particularly the weight of the fruits. After 

 grading the finest fruits are wrapped first in a white and then in a colored paper, and packed 

 into boxes whose gross weight does not exceed 5 kilos. Usually such boxes contain from 12 

 to 20 fruits, though there may be as few as 9 or as many as 32. The less choice fruits are 

 packed into cases which contain from 400 to 500 fruits arranged in 6 layers, with a gross 

 weight of 55 to 60 kilos, and into half-cases which contain from 180 to 200 fruits arranged in 

 5 layers, with a gross weight of 25 to 30 kilos. There are also special cases for special purposes. 

 The price received for the fruit varies with the quality and quantity available. Over a ten- 

 year period, for the best fruits this has ranged from 10, to more than 50 cents a pound; very 

 large individual specimens selling readily for 80 cents each. The inferior grades sell for less.
