If the greenhouses are constructed to gro^^ 

 plants on the solid bed instead of raised 

 benches, the same method of cultnation 

 should be followed and not more than 5 or ( 

 inches of soil should be used on the surfan 

 have a thoroughly drained border m ill 

 other respects cultivation would be the same 

 as for bench system. After the plants [,tt 

 into thorough, strong, vigorous growth m\ 

 producing abundance of flowers, sa> frc iii 

 Christinas onwards, a mulching of well 1 

 composed manure every five or six \ 1 

 very limited quantities will be beii.ii 

 if the plants have made extra strong 



and all the soil is occupied with i t i ii 



benches towards the end of Februar\ li |iii i 

 manure can be applied once in very thiee i 

 four weeks with considerable benefit Thi 

 treatment should carry the plants siicces 

 fully through to the end of their bloomiu^ 

 season. 



If the plants are kept in good, healthy vi^ 

 orous condition they could be carried through 

 for a second season's work if necessary T 

 do this it would be necessary to dry them ell 

 somewhat, say through July and part of Au 

 gust for four to six weeks, so as to ripen tli 

 wood thoroughly without wilting the leavt 

 completely. Then they could be pruned bi k 

 to good, sound, plump eyes at the base of th 

 strong shoots and all the small spray grow tl 

 cut out. Then the plants can be lifted with 

 a good ball of earth, so as to save as much rt 

 the roots as possible, replanted into new 

 soil, and practically treated the same i 

 young stock. 



If grafted stock is preferred instead r t 

 own-root cuttings as above described, they 

 can be treated according to regular instruc- 

 tions given by many authorities on grafting. Cultiv 

 tion of these is in all respects identical with the abov 

 except as to the rooting of the cuttings.

ROSMARINUS (Latin, sen-rfpic; the plant is common 

 on the chalk hills of the south of France and near the 

 seacoast). Labidlw. Rosemary is a nearly hardy sub- 

 shrub, with aromatic leaves which are used for season- 

 ing. It has small, light blue flowers, which are much 

 sought for by bees. Oil of Rosemary is a common 

 preparation in drug stores. It is a volatile oil distilled 

 from the leaves. The Ivs. are also used in making Hun- 

 gary water. In northern herb gardens it lasts for years 

 if given well-drained soil and some winter protection. 

 Franceschi recommends it for hedges in S. Calif., espe- 

 cially for dry and r<ick\ ]il.i.-c s m .u t\\<- ( u-\^{
