In certain stages of plant life the energyof the plant seems directed into the channels ofblossoms rather thaa foliage. At this tirne phos-phates and potash are demanded much more thannitrogen. The chemical phosphate of potash hasfifty per cent, phosphoric acid and thirty-three percent, of potash, and dissolves in water. Such feed-ing should give the needed incentive for blooming,and support well the bloom. Potash. For potash we have the animal manures fromwhich it can be obtained quite easily, and woodashes. As chemicals there are the sulphate,, muriateand carbonate. These chemicals are used out-of-doors mostly, but Indoors there are often seriousobjections to their The Dawson Rose at Twin Oaks, Wa shington, D. C. Commercial Fertilizers. About a generation ago commercial fertilizerscame into use. They were more portable and dur-able than animal manures, and answer for farming,composed of insoluble materials, as blood, groundor dissolved bone, tankage, and usually with somecheap soluble chemical of the list already are not very satisfactory for rose culture evenoutside. Their variable composition, insolubility fortank use, often liarmful ingredients, and low foodvalue render them undesirable for bench perhaps fifteen per cent total plant foods,with three quarters useless filler, they yet mark adistinct step toward an ideal soluble fertilizer, andaway from the old disagreeable manures. Rose soil under glass is often mixed with boneand dung (with the latters numerous living retinue)and sometimes lime. Bu
