1395. BioLETTi, Frederic T. Permanent demonstration vineyards in California. Proc. 

 Amer. See. Hort. Sci. 17: 73-79. 1920 [1921]. — The author presents an outline of the methods 

 used to carry practical information to the growers. Details of the working arrangement with 

 the owners of vineyards are noted. — H. W . Richey. 



1396. Blair, W. S. Fruit growing in Nova Scotia. Proc. Amer. Pomol. Soc. 35: 157- 

 161. 1917 [1919]. — The principal fruit districts are confined to the counties of Kings, Anapo- 

 lis, and Hants, where a total of over 30,000 acres of apples are planted. Most of the crop pro- 

 duced is exported each year. There are 130 apple warehouses throughout the fruit section, 

 40 of these are owned by companies which have aflBliated, forming the United Fruit Companies 

 of Nova Scotia Limited. This company purchases most of the spray materials, fertilizers, 

 seeds, etc., for the different members. Spraying is carefully done. Bearing orchards are 

 valued at $500 per acre. The cost of producing apples before 1917 was estimated at $1.75 

 per barrel. Most of the crop is packed in barrels, and inspectors enforce a good standard. 

 Varieties most commonly grown are Gravenstein, Ribston, Blenheim, Tompkins King, North- 

 ern Spy, Stark, and Ben Davis. — E. C. Auchter.

 of progress. Proc. Amer. Soc. Hort. Sci. 17: 243-249. 1920 [1921]. — This paper reports work 

 done chiefly with selected plants of the "lowbush" blueberry, Vaccinium pennsylvanicum. 

 Since the swamp lowbush blueberry, V. canadense, blooms and ripens its fruit a little later, 

 this species has been used for the past 2 seasons. V. corymbosum has not been able to with- 

 stand the severe winters, but more seedlings and hybrids have recently been obtained from 

 Dr. F. V. Coville for further trial. It was found that 1-year old rooted shoots furnished the 

 best propagation material. A table is included showing the effect of different cultural treat- 

 ments upon the stand and vigor of plants. After 3 years trial only 3 treatments, cultivating, 

 cultivating and shading, and the 2-inch peat mulching, were retained. Manure proved to be 

 detrimental, probably due to its alkaline nature. As regards effect on vigor and yield it 

 appears that cultivating and peat mulching are about equally satisfactory. The number of 

 berries in the clusters on the cultivated plots was greater than on other plots, and considerably 

 greater than on plants grown in the wild state. The benefits derived from cultivation appear 

 to be greater than those from efforts to renovate wild plantings. — H. W. Richey. 



1398. Chandler, W. H. Some responses of bush fruits to fertilizers. Proc. Amer. Soc. 

 Hort. Sci. 17: 201-204. 1920 [1921]. — About ^'^ acre each of American gooseberries, currants, 

 American red raspberries, black raspberries, and blackberries was planted in 1914. At the 

 beginning applications were made at the rate of 100 pounds of potassium chloride, 400 of 

 acid phosphate, and 200 of sodium nitrate per acre. As the plants grew the applications were 

 gradually increased until in 1920 the plots received treatments equivalent to 300 pounds of 

 potassium chloride, 600 of acid phosphate, and 350 of sodium nitrate per acre. Where manure, 

 tankage, or dried blood was used, amounts were applied furnishing approximately the 

 amount of nitrogen applied to a plot receiving sodium nitrate. — In comparison with corn, 

 planted in a portion of the gooseberry and currant plots where the berry plants were removed, 

 the evidence seemed conclusive that gooseberries showed no response to phosphorus. Since 

 the soil wes so poorly adapted to blackberries and red and black raspberries, it was not possi- 

 ble to determine whether or not any of them would respond to phosphorus though certainly 

 none responded strikingly. — In plots of black raspberries and red raspberries receiving nitro- 

 gen, the total cane growth was respectively 1.004 and 1.87 times that of plots receiving no 

 nitrogen; the blackberries showed no measurable response. The application of nitrogen 

 benefited the red raspberry much less in yield than in growth, possibly because the variety 

 used (Cuthbert) suckers very readily. — The currants made no measurable response to any 

 element. Gooseberries responded to nitrogen and possibly to potassium, the response to 

 manure being greater than to complete mineral fertilizers. In the case of the Cuthbert rasp- 

 berry, the response to sodium nitrate seemed to be greater than to an equal amount of nitrogen 

 in manure, tankage, or dried blood. — //. W. Richey.
