2d What kinds of these are best suited for growing in 

 pots, and what is the soil used ? Cattleyas, Dendrobiums 

 and Odontoglosxums do well in coarse chopped peat, pots 

 nearly filled with crocks ; Coelogyne and Lycaste, coarse, 

 sandy peat, with chopped, half decayed leaves ; Cypripe- 

 diums, Phajus and Zygopetalums in peat and loam, and a 

 little rotten .manure ; Phalcenopsis, Vandas and Laelias 

 do well in baskets, pots or small pans, in chopped sphag- 

 num ; the drainage must be perfect. Calanthes, chopped 

 sods of sandy loam, with not over fine leaf mould ; the 

 plants must be made steady with stakes and copper wire. 



3d What kinds are suited to grow on bark or cork, or 

 other such material, and what compost or other substance 

 is used ? Cattleyas, Lael/ias, Phalcenopsis, Vandas and 

 Dendrobiums do well on blocks of cork, rafts, cylinders, 

 etc., with sphagnum or other moss; but take more care, as 

 they dry so quickly. A plant on a block will take water 

 tAvice a day, the same in a basket only once in two 

 days ; blocks can be hung overhead, but the expense of 

 dipping the blocks twice a day in water would, for a 

 florist, not be remunerative. 



4th At about what night and day temperature should 

 such varieties as you have named be grown ? Phalce- 

 nopsis, Vandas, Dendrobiums and Cypripediums in win- 

 terthermometer, sixty to sixty-five degrees at night, to
