or green feeding from the time of heading until the seeds are in the dough stage- 

 Both the seed and the fodder are rich in carbohydrates, and are best fed in connec- 

 tion with materials containing protein. 



The culture of the sugar beet, <i. W. Shaw {California Sta. Circ. IS, pp. ?1, 

 figs. s). This circular gives detailed information on sugar-beel culture as practiced in 

 tlic most successful beet-growing sections. The adaptability of varieties, the kind 

 of soils suited to the crop, the preparation of the soil in the fall and spring, irrigation 

 of beets, and their cultivation and harvesting are discussed. 



Experiments with sugar beet, < i. Clarke {Chelmsford, England: County Tech. 

 Labs., 1906, pp. :;. pi. I, jigs. S). ( Jooperative culture tests with 5 varieties of sugai 

 beets were carried on in Essex in L905 in five different localities. An average yield 

 of 18. 3 tons per acre, with L6.7 percent of sugar in the beet and a purity of 84.7, 

 was secured. 



Evaporation by the sugar cane plant, Z. K \ \ii.i;i.i\<, | Meded. Proefstat. Suiker- 

 riet West-Java, 1905, No.87,pp. 22). Several experiments in which the water evapo- 

 rated by the cane plant under differenl conditions was determined are reported. 



In one test with well-developed canes the quantity of water evaporated during 24 

 hours, when the plants were exposed to the direct rays of the sun only during the 

 afternoon, averaged from 183 to 292 gm. per plant. In another instance a plant of 

 about 6 weeks' growth and exposed to the sun during the entire day evaporated 350 

 gm. in 24 hours. The average results with 9 different plant- 5 mos. old show an 

 evaporation of If liters of water per day. Further data on the evaporation of watei 

 by sugar cane are reported, and it is pointed oul thai the factors mosl largely influ- 

 encing this activity of the plant arc the distribution of the roots, physical condition 

 of the soil, soil moisture content, leaf surface, temperature, and sunlight conditions. 

 The effect of the curling of the leaf on evaporation is discussed. 



Proceedings of the third annual convention of the Interstate Sugar Cane 

 Growers Association {Proc. Inters/at, Sugar Cane Growers Assoc, S {1905), pp. 

 110). — Among a scries of papers bearing on the sugar-cane industry several treat of 

 the culture of cane and its cost of production in different southern states. 



Notes concerning seed wheat, (I. YV. Sn \w i California Sta. Circ. 16, pp. 8, figs. 

 2). — This circular reviews previously noted results secured at a number of stations 

 with seed wheat grown on different soils, selected from different sized heads, and 

 separated into large, small, heavy, light, plump, and shriveled kernels. Directions 

 for the prevention of smut by the formaldehyde, copper sulphate, and hot water 

 methods are given. 



HORTICULTURE. 



The farmer's vegetable garden, .1. D. Lloyd ( Illinois Sta. />'"/. 105, pp. 1 52 -205, 

 pis. 4, figs. < s ', dgms. S). — This bulletin presents details of the management of a half 

 acre of ground used as a vegetable garden for 5 years beginning in 1900. 



The cost of preparing and maintaining the garden each year, vegetables planted. 

 and the quantity harvested, and their value, have been systematically recorded. 

 The half acre was made in the form of a rectangle and the rows planted lengths ise 

 of the garden and far enough apart to permit horse cultivation. The following table 

 shows the value of the products obtained from the garden for each of the •"> year- of 

 the experiment, the total expense each year, ami the net profits:
