170 HORTICULTURE [Bot. Absts., Vol. VI, 



lage and Sons, of Haarlem. Because of the large size, form, consistency, color, and keeping 

 qualities of the flowers, the long stems on which they are borne, and the general hardiness of 

 the plants, the several varieties are being widely planted by amateurs. Typically this class 

 of tulips should be of solid color; the variegated forms should be classed as Rembrandts. 

 Most of the varieties, however, are apt to become variegated in color under certain climatic 

 conditions or if allowed to remain for some time without transplanting to a new soil. The 

 more intense colors are least subject to change whereas the violets and lilacs are most likely 

 to become modified. — E. J. Kraus.

 Jan., 1920. — This species was introduced in 1904 by E. H. Wilson, from the mountains of Se 

 Tchuen, western China. It is a beautiful shrub, scarcely more than a meter in height, hardy, 

 interesting for its almost persistent foliage, becoming yellow-red in November and December, 

 and its numerous coral red fruits which are conspicuous from October to severe cold weather.

VEGETABLE CULTURE 



1174. Enfer, V. Premiers semis de pois. [The first sowings of peas.] Rev. Hortic. 

 [Paris] 92: 20-21. Jan., 1920. — General directions are given regarding time of planting, prep- 

 aration of soils, selection of varieties, and harvesting. With the approach of warm weather 

 the vines are apt to become diseased. Copious watering and the application of copper sulfate 

 (2 grams per litre of water) will aid in preventing this difficulty, but after April 1 it is prefer- 

 able to sow varieties having wrinkled seeds since they will resist the bad effects of warm 

 weather to a greater degree than will the round seeded types. — E. J. Kraus.

 fications of an evaporator of the horizontal tunnel air-blast type used successfully in the 

 drying of grapes and prunes are given. Dipping of grapes in dilute boiling lye solution 

 approximately doubled the rate of drying. No constant difference in yield could be found in 

 sun-drying and evaporation. Unless heavily sulfured, dried grapes of 30 per cent or more 

 moisture had poor keeping qualities. When dried, wine grapes could be seeded successfully 

 but the loss during the process was excessively large. — A. R. C. Haas.

 method of profitably utilizing the crop of wine grapes in California. — A. R. C. Haas.
