852. Bouquet, A. G. B. Factors affecting shrinkage and condition of broccoli. Oregon 

 Agric. Exp. Sta. Crop Pest and Hort. Rept. 3 : 40^1. 1921. — The shrinkage of heads is very 

 much greater if the latter are cut at any time after prime condition. It is preferable even 

 to cut the heads immature rather than when they show signs of curd separation. — E. J. Kraus. 



853. Bouquet, A. G. B. Vegetable greenhouse crops in relation to the use of the green- 

 house for one season. Oregon Agric. Exp. Sta. Crop Pest and Hort. Rept. 3: 33-35. 1921. — 

 The author gives suggestions on crops wliich can be produced in the autumn. — E. J. Kraus. 



854. Pitt, J. M. Farmers' experiment plots. Onion trials on the Manning river. 1920- 

 21. Agric. Gaz. New South Wales 32: 261-264. 2 fig. 1921.— The total onion acreage for 

 New South Wales for 1919 was only 335. Yields ran from 2.5 to 4.5 tons per acre. The crop 

 is marketed from November to IMay and the price secured approximates $300 per acre. Seed- 

 lings were transplanted into the field in July (winter) and the harvest ran from November to 

 January. Most varieties responded very favorably to irrigation. The maximum yield was 

 secured from White Early Barletta, which gave 7.6 tons per acre. — L. R. Waldron.

855. Christie, A. W. Dried, evaporated or dehydrated? Associated Grower 1^: 20, 

 21. 1920. — The term "dried" is applied to all fruits and vegetables preserved by the removal 

 of moisture, irrespective of the method of removal. To the class dried by artificial heat, 

 the names "evaporated" and " dehydrated" are applied, as distinct from "sun-dried." — E. 

 L. Overholser.

 evaporator. Associated Grower V: 8, 40, 41. 1920. 



857. Gaj6n, Carlos. Las rosas para perfumeria.-Su historia. [History of rose growing 

 for perfume] Rev. Agric. [Mexico] 5: 351-358. 13 fig. 1919. — A popular account of the grow- 

 ing of roses for perfume as it is carried on in Spain, Bulgaria, Algeria, India, and France. — 

 John A. Stevenson.

 Grower r: 4-5, 46. 1920. 



859. JuRiTZ, Chas. F. Apricot kernel oil and its congeners. South African Jour. Indust. 

 3: 1052-1057. 1920. — Descriptions are given of the oils obtained from almond, apricot, and 

 peach pits, with a table showing the composition of apricot-kernel oil as well as the following 

 constants: Specific gravity, saponification value, acid value, refractive index at 40°C., and 

 iodine value. — A. J. Pieters.

881. Schmidt, R. Handling the peach crop. Associated Grower 1^: 7, 43. 1920. — Trees 

 should not be shaken to obtain peaches for drying. Many of the peaches thus collected are 

 relatively green, have a low sugar content, and yield a poor product; they also lose 10 per cent 

 more in weight than an equal weight of mature peaches. — E. L. Overholser. 



862. Schmidt, R. Sugar content testing for raisins. Associated Grower 1^: 9, 44. 1920. 

 — The author recommends the saccharometer as the most convenient instrument for sugar 

 content determinations. The results are sufficiently accurate for ordinary practical purposes 

 provided the necessary temperature corrections are made. — E. L. Overholser. 



863. Wiegand, E. H. Some investigations on prune drying. Oregon Agric. Exp. Sta. 

 Crop Pest and Hort. Rept. 3: 52-57. Fig. 12-15. 1921. — Drying is hastened by dipping the 

 fruit in boiling water or lye solution. A high humidity of the drying air has a tendency to 

 open the pores of the skin and prevent charring. High humidity accompanied by rapid air 

 movement increased the rate of drying, slow movement decreased the rate. — E. J . Kraus.
