26 EXPERIMENT STATION RECOED. 



potatoes. The results obtained iu the cases where the flnorid was added to the 

 leucite as compared with the cases where sulphate of potash was used in vary- 

 ing amounts were on the whole favorable to the combination of leucite and 

 Uuorid. but no absolute conclusion can be stated. 



Horse-hoof parings {Jour. Dept. Agr. West. Aust., 17 (1908), A'o. 1, p. 551).— 

 It is stated that this material furnishes a good manure for fruit trees and 

 vines, especially on sandy soils where by slow decay it will yield a gradual 

 supply of nitrogen. The material contains from 8 to 12 per cent of organic 

 nitrogen and 6 to 10 per cent of phosphoric acid. It is recommended that the 

 parings be thrown into a heap, sprinkled with sulphate of potash and protected 

 from rain, and allowed to decompose for about 6 months. It will then be 

 found to be a good manure if mixed with loam, old mortar, or unleached ashes 

 before application. 



Analyses of fertilizers sold in Maryland, H. B. McDonnell et al. (Md. 

 Agr. Col. Quart., 1909, No. JjS, pp. 55).— This bulletin reports the results of 

 fertilizer inspection during the last half of 1908. 



Inspection and analyses of commercial fertilizers on sale in the State, 

 W. F. Hand et al. {Mississippi Sta. Bui. 115, pp. 3-72). — The results are re- 

 ported of analyses of 526 samples inspected during the season of 1907-8. The 

 pecuniary advantage of buying high grade fertilizers is set forth, and it is 

 stated that the demand on the part of farmers for low grade mixtures is due 

 to an incorrect idea of the actual value of fertilizers. 



Analyses of fertilizers, F. W. Morse and B. E. Curry (Xcw Hampshire *S7a. 

 Bui. IJ/O, pp. 237-242). — Analyses of about 100 brands collected by the agent of 

 the State board of agriculture are reported. Attention is called to the fact 

 that a large number of the brands were slightly low in nitrogen. 



Analyses of commercial fertilizers, B. L. Hartwell, J. F. Morgan, and 

 L. F. Whipple (Rhode Island .S7«. Bui. 132, pp. 35-51). — This bulletin contains 

 analyses of sami)les of commercial fertilizers collected during the year 1908 not 

 previously reported (E. S. R., 20, p. 522). The question as to whether the manu- 

 facturer should be allowed to supply au order for fertilizer constituents mixed 

 according to a specified formula without being required to pay an additional 

 license fee, " provided the goods are labeled with the formula according to which 

 they were mixed," is discussed. It is held that an explicit statement of the 

 character of the mixture " would be in effect a guaranty by the manufacturer 

 and a protection to the inirehaser." 



Analyses of commercial fertilizers, ,1. Thompson {Naslrville, Tenu.: t^tatc 

 Dept. Agr., 1909, pp. 51). — This is a report of insi)ection of fertilizers in the 

 State during the year ended December 31, 1908. It is stated that " the various 

 manufacturers of commercial fertilizers sold in the State of Tennessee from 

 December 19, 1906, to December 19, 1907, .38,794 tons ; from December 19, 1907, 

 to December 19, 1908, 46,384 tons. The year 1908 shows the largest increase 

 ever recorded in the sales of fertilizers in this State. There has been a large 

 increase in the sale of complete fertilizers, due largely to the trucking and 

 tobacco interests in Tennessee." 



Fertilizers, J. T. Crawley {Estac. Cent. Agron. Cuba Bui. l.'i. English Ed., 

 pp. 35). — This bulletin is intended to be educational in character and gives the 

 analyses of fertilizers and fertilizing materials examined at the Cuban Experi- 

 ment Station during recent years, with such facts as are considered necessary to 

 a proper understanding of the nature and use of fertilizers. 



It is stated that the need of fertilizers in Cuba is already apparent and is 

 I'apidly increasing, and that planters are beginning to experiment with them to 

 a considerable extent. Their nature and use are. however, so imperfectly under- 

 stood that the station has undertaken rather extensive experiments with fer-
