 includes plans and descriptions of the barn and slieds of the station, 

 and of tlie stable <ittin<is, includiiii;' four kinds of cattle stanchions wliicli 

 liave been tried; an account of held experiments with vyv, oats, corn, 

 and potatoes ; and a list of donations. 



IJ.rprrimoit.s irifh ri/e (p]). 13-15). — Rye was£i;To\vn upon land in wiiicli 

 crops of buckwheat and of oats and rye had been i»lowed the previous 

 year, and to which muriate and sulphate of potash, seaweed, stable 

 manure, and ''mixed chemicals" Avere each a|>])lied separately. Tlie 

 tabulated I'csults show the largest yields of grain to have been Avith 

 stable manure and with seaweed. "We believe that Avith a good press 

 for baling the straw, rye can be profitably groAvn in this section of the 

 State." 



Experiments icitli (uds (pp. 15-17). — These Avere on 9 fourth-acre plats, 

 1 of which receiA^ed 233.75 pounds each of Earle's Horsefoot Guano, 

 costing $14.02 ; 3 an equal value of a mixed fertilizer composed of muriate 

 of potash, nitrate of soda, bone superphosphate, fine ground bone, tank- 

 age, and ammonium sulphate; and 2 remained unnmnured. "The mixed 

 fertilizer at the same cost, furnished approximately 11.5 pounds more of 

 l>hos])horic acid, 20.0 pounds more of nitrogen, and an equal amount of 

 piotash, allowing that the guano contained the full amount of the higher 

 guaranty which commercial fertilizers seldom reach." Oats were sown 

 broadcast on G i)lats and drilled in on 3 plats. The plats were overrun 

 Avith charlock, Avhich was pulled up, but the crop was considerably 

 i 1 1 J u red . According to the results, as tabulated, the drilled plats y iel ded 

 about 11 per cent more grain and straw than those sown broadcast, 

 and under like conditions the "mixed chemicals at the same cost gave 

 34.0 per cent more grain and 13.7 per cent more straw than Earle's 

 Horsefoot Guano." 



Experiments icitli corn (pp. 18-23). — The yields of corn in 1889 and 

 1890 are tabulated for 17 tenth-acre plats manured with various com- 

 ])inations of barnyard manure, seaweed, and chemicals. The corn Avas 

 planted in hills 3 feet apart each way. The indications were " that the 

 soil is A^ery deficient in phosphoric acid and that unless that element 

 is supplied the expenditure of money for other fertilizing elements is a 

 positive waste. The same money value of stable manure j)roduces 

 better results than seaweed." 



Experiments icith potatoes (pp. 23-27). — Potatoes Avere raised on 24 

 fortieth-acre plats on aa hich were applied ammonium sulj^hate, nitrate 

 of soda, ground bone, and barnyard manure, singly and in A^arious
