160 gallons of molasses were obtained. The sugar sold at 3 cents per 

 pound, or $72; the molasses at 35 cents per gallon, or $56. Total for 

 one and one half acres, $128, or per acre, $85.35." These results, which 

 were obtained from poor land in the dry seasou^ are considered very 

 encouraging.

Sugarcane bouer and its parasite, H. A. Morgan, B. S. A. 

 (pp. 215-228, illustrated). — A j)reliminary report on the sugarcane 

 borer {Chilo saccharalis), the investigation of which was begun at the 

 Louisiana Stations in the fall of 1890. An account of the life history 

 of the insect is given, with suggestions as to means for its repression. 

 A soldier beetle {Ghauliognathus pennsylvanica) was found to be a para- 

 site on the sugar-cane borer.

Inspection of fertilizers, W. B. Jordan, M. S., J. M. Bartlett, 

 M. S., AND L. H. Merrill, B. S. (pp. 1-35). — Analyses are tabulated 

 for 91 samples, representing 43 brands of commercial fertilizers 

 collected within the State during 1889. Brief remarks are also made 

 on the observance of the fertilizer law, sampling, methods of analysis, 

 valuations, and home mixing. 



Quality of nitrogenous materials in su2^erphosphates. — "The nitrogen of 

 dried blood, dried flesh, cotton-seed meal, and similar high grade nitrog- 

 enous materials is very largely dissolved by digestion in a pepsin 

 solution, while that of horn, hoof, and leather is much less aifected by 

 this treatment." 



The results of determinations of the solubility in pepsin solution of 

 dried blood, cottonseed meal, ground bone, dried flesh, dried fish, fish 

 scrap, tankage, wool waste, leather, horn and hoof meal, and of the 

 organic nitrogen in 39 brands of commercial fertilizers analyzed by 

 the station are tabulated. 



The degree of solubility for cheap and inferior " ammouiates," such as horn, hoof, 

 leather, and wool waste is seen to vary from 4.8 per cent to 37.8 per cent, while in the 

 case of dried blood, cotton-seed meal, dried and ground flesh, dried fish, iish scrap, 

 and ground bone the average percentages of the different trials range from 70.9 per 

 cent to 97.3 per cent. 



In the 39 brands tested the solubility of the organic nitrogenous material ranges 

 from 21.3 per cent to 83.4 per cent. In 3 cases the percentages are below 40 per cent, 

 in 3 between 40 and 50 per cent, in 4 between .50 and 60 per cent, and in 29 over 60 

 percent. * » * A close grading of the quality of the nitrogenous matter of super- 

 phosphates does not seem to be possible by this method. 



Cattle foods (pp. 36-68). — The analyses are given of hay from 

 timothy, wild oatgrass, redtop, blue-joint grass, and alsike clover 

 raised in 1888, and for comparison the composition of these same 

 grasses for several seasons past. Experiments to determine the
