find to be due to a bacterium which they promise to describe in a 

 subsequent paper. Washing the fruit with water before crushing, scru- 

 pulous cleanliness in utensils, &c, fermentation to dryness where this 

 is possible, the raising of the acidity of the cider by suitable blending, 

 storage at alow temperature, and the bottling of the cider in January 

 or February instead of in April or May, are recommended as means 

 of prevention. — F. J. C.

Citrus Groves ; Sites, Soils, and Varieties for, in the Gulf States. 



By P. H. Rolfs (U.S.A. Dep. Agr., Farmers' Bull. 538, May 16, 1913).— 

 Owing to the numerous requests which have been received by the 

 Department of Agriculture for information regarding the growth of 

 oranges and other Citrus fruits in Florida, we get the present useful 

 bulletin. The publication is divided into three parts: (1) Sites, soils, 

 and varieties for Citrus groves in the Gulf States ; (2) propagation of 

 Citrus trees in the Gulf States; and (3) culture, fertilization, and frost 

 protection of Citrus groves in the Gulf States. — A. D. W.

 This is a resume of the various operations carried out in the cultivation 

 of Citrus trees — nuisery management, selecting seeds, preparation

 long, slender stem, a crown of lance-shaped leaves, about three feet 

 in length. The small dark-red flowers form grape-like clusters. The 

 plant is dicecious. — S. E. W. 



Clematis montana var. Wilsonii. By S. Mottet (Rev. Hort. 

 pp. 322-324, July 16, 1913 ; 1 ill.). — A description of this and other 

 Chinese introductions by Mr. E. H. Wilson. The flowers of this 

 variety are larger than those of C. m. grandiflora, are more massed, 

 and produced later, i.e. summer rather than spring, and sometimes 

 also in the autumn. Foliage more ample and with goffered edges, 

 giving an altogether different aspect from C. m. grandiflora. It is 

 pointed out that some of the former introduced would appear by 

 these differences to justify specific rather than varietal rank. Highly 

 recommended for cultivation.— C. T. D.
