Corn experibient (pp. 3-G). — An exi)eriment on live plats, the size 

 of which is uot given. One thousand pounds of " pot ammoniac," 1,000 

 pouiuls of blood and bone, 1,000 pounds of black cotton-seed meal, ami 

 1 ton of a compost made by mixing 2,000 pounds of stable manure and 

 333 pouuds each of cottonseed meal, kainit, and acid phosphate, were 

 each used on one plat, the renuiining plat receiving no fertilizer. The 

 increased yield over the unfertilized plat, aud cost of the increased yield 

 per bushel are giveu for each plat. The largest yield was with cotton- 

 seed meal, but the cost of the corn per bushel was lowest with the

 Pii. D. (pp. 11-18). — A popular discussion of the chemistry of feeding^ 

 together with analyses, by J. J. Earle, B. A., of beggar weed {Desmodium 

 moUc), cotton-head weed {Froelichhi Jforidana), sandspur grass (Cmu'/o-ms 

 trihuloides), wire grass {Aristida purpurea), purslane {rortidaca olera- 

 cc(i)j, crab-grass [Panicum sanguinale), bull grass {Elcusinc (Vfjijpfiaca), 

 Louisiana grass {Paspalum platycaulc), Spanish moss {Tilland.sia usne- 

 oidcs L.). Beggar weed {Desmodium molle) is mentioned as deserv- 

 ing of consideration for feeding purposes. Assuming its digestibility 

 to be equal to that of an average hay, the nutritive ratio of this mate- 

 rial is given as 1 : 7. "Beggar weed will make two crops of hay. 

 The second crop is said to be less stemmy than the first, and is 

 regarded by some as the very best hay when properly cured."
