No. 4, January, 1921] HORTICULTURE 265 



The growing of winter green manure crops has not entirely overcome this difficulty. Better 

 success has been achieved by growing field beans in the orchard or a strip of alfalfa between 

 the rows. The author proposes a combination fruit and dairy farm as the best means of 

 maintaining the soil fertility in California orchards. This farm should preferably be oper- 

 ated by two men — one a fruit grower and one a dairyman. This plan besides furnishing 

 manure for the orchard would better distribute the labor. — //. .V. Vinall. 



1820. Howard, \V. L. The value of the different roots as stock. Better Fruit 14 10 : 10-20. 

 1920. — A brief discussion is given of the value of apricot root stock for prunes and the French 

 and Japanese root stocks for pears. — A. E. Murneeh. 



1821. Jouin, E. L'Horticulture in Lorraine desannexee. [Horticulture in disannexed 

 Lorraine.] Rev. Hortic. [Paris] 92: 44-45. 1920. — Previous to 1870 a broad professional and 

 amateur interest was manifested in horticulture. This has declined appreciably since then, 

 though recently there seems to be a new and awakened interest. There is but one important 

 public garden, located at Metz. The hills on the left shore of the Moselle, the Saar basin 

 and the Palatinate afford a considerable tree and small fruit industry. There are many small 

 greenhouses which do a local business in easily grown plants. There is an extensive vegetable 

 growing industry at Metz, and on both banks of the Moselle. The nursery business has always 

 been the most extensive branch of horticulture in Lorraine. At various places good specimens 

 of various exotic trees may be found. — E. J. Kraus.

1824. Lamproy, E. Le rajeunissement des pechers en plein vent. [Rejuvenation of stand- 

 ard peach trees.] Rev. Hortic. [Paris] 92: 32-34. Figs. 7-8. 1920 — The method of rejuvena- 

 tion consists in a heavy heading-back, even of the very large branches, close to a lateral; so 

 that the process is at the same time also one of thinning out. Larger yields of better fruit 

 were secured from the pruned trees than from those which were left unpruned and had been 

 neglected for some time. The cuts should be made with a fine-toothed saw, trimmed with a 

 sharp knife, and covered with mastic. Attention is directed to the fact that this same method 

 of pruning peach trees was advocated in the middle of the nineteenth century by Naudin et 

 Decaisne in their "Manuel de l'amateur des jardins" 4: 423. — E. J. Kraus. 



1825. Landry, R. Le transport des primeurs par avion. [Transporting early crops by 

 aeroplane.] Rev. Hortic. [Paris] 92 : 83. Fig. 20. 1920. — A shipment of forced strawberries 

 of the variety Doctor Morere was sent by aeroplane on March 18, 1920, by Mr. de la Celle, 

 from Saint-Laurent-du-Var to Paris. — E. J . Kraus.

1827. Lewis, C. I. Pear culture at home and abroad. Better Fruit 14 10 : 23-24. 1920 — 

 A popular article on pear growing, with particular reference to the northwestern United 

 States. — A. E. Murneeh. 



1828. Noren, C. A. A practical demonstration of fruit thinning. Better Fruit 14 12 : 

 15-16. 1920. — Four sets of comparisons were made of well thinned and poorly thinned 

 orchards. In every case fruit from poorly thinned orchards was smaller in size and lacked the 

 necessary color to grade it as "extra fancy." The writer believes also that proper thinning 

 lessens the strain on fruiting spurs and diminishes the habit of alternate bearing. — A. E. 

 Murneek.
