Manures for passion vines {Agr. Gaz. New South Wales, 14 {1903) , No. 3, pp. 

 252-255). — Tlie effect of a number of different fertilizers and combinations on the 

 yield of passion vines is reported. The best results were obtained by the use of 4 

 different formulas, 3 of which are as follows: (1) 52 oz. dried blood, 9 oz. super- 

 phosphate, 6j oz. potassiuui chlorid per vine; (2) 43 oz. nitrate of soda, 9 oz. super- 

 phosphate, 6i oz. potassium chlorid per vine; (3) 32 oz. sulphate of ammonia, 18 oz. 

 superphosphate, S oz. sulphate of potash per vine. The vines manured with com- 

 plete fertilizers in tliis experiment gave heavy yields of fruit and appeared in a 

 thrifty condition, while uninanured vines appeared to have become exhausted, 

 although i)rodueing little if any fruit.

FORESTRY. 



The woodlot, II. S. Graves and R. T. Eisher ( U. S. Dept. Ar/r., Bureau of Forestry 

 Bui. 42, pp. 89, pis. 4, figs. 30). — This bulletin, which is called a handbook for owners 

 of woodlands in southern New England, describes the forests of southern New Eng- 

 land and suggests methods for the improvement of their condition. The handbook 

 is prepared especially for the owners of woodland and its purjjose is to show how 

 second-growth wood, which comprises the principal forest area of New England, 

 may be treated in order to yield larger returns than under the present methods. 

 The methods of cutting which are recommended are simple and can be applied with 

 lieneficial results under conditions now existing in that region. The practice recom- 

 mended by the authors for these second-growth forests consists of thinning the woods 

 which are not mature so as to improve the conditions of growth and utilize material 

 which is otherwise wasted, cutting in mature woods in such a way that the succeed- 

 ing growth will follow quickly and be composed of valuable species, the pruning — 

 which is only practicable in certain sorts of stands — protecting forest property against 

 fire, and restocking waste land by planting and sowing. A number of diagrams are 

 given which are sketched from actual conditions showing the application of the 

 methods suggested for improvement cuttings.
