 the plants are allowed to get dry in ;ii 

 or too high a temperature is carried. 'I 

 be avoided by liberal syringing on al 

 days, thoroughly soaking the under k t 

 all the foliage. 



If the greenhouses are constructed to glo^ 

 plants on the solid bed instead of raise i 

 benches, the same method of cultiviti i 

 should be followed and not more than ^ oi i 

 inches of soil should be used on the suitict 

 have a thoroughly drained border m II 

 other respects cultivation would be the s-iu 

 as for bench system. After the plants t t 

 into thorough, strong, vigorous growth an \ 

 producing abundance of flowers, saj fron 

 Christmas onwards, a mulching of well dr 

 composed manure every five or six w 1 

 very limited quantities will be beneti i 1 

 if the'plants have made extra strong, 

 and all the soil is occupied with root i 

 benches towards the end of Februarj 1 j 

 manure can be applied once in very three 

 four weeks with considerable benefit Tin 

 treatment should carry the plants succes 

 fully through to the end of their bloomin^ 

 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 c 11 

 somewhat, say through July and part of An 

 gust for four to six weeks, so as to ripen tl l 

 wood thoroughly without wilting the leave 

 completely. Then they could be pruned bat k 

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

 strong shoots and all the small spray growtl 

 cut out. Then the plants can be lifted witl 

 a good ball of earth, so as to save as much r t 

 the roots as possible, replanted into new 

 soil, and practiciUy treated the same ■> 

 young stock. 



If grafted stock is preferred instead cf 

 own-root cuttings as above described, they 

 can be treated according to regular instruct 

 tions given by many authorities on grafting. Cultiva- 

 tion of these is in all respects identical with the above, 

 ■except as to the rooting of the cuttings.

EOSMAEiNDS (Latin, sen-deic; the plant 

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

 seacoast). LabiMa. 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 rocky places near the coast. 



Generic characters : calyx 2-lipped; posterior lip con- 

 cave, minutely 3-toothed; anterior 2-cut; corolla with 

 posterior lip erect, emarginate, anterior lip spreading, 

 3-cut, the middle lobe longest, concave, declined: per- 

 fect stamens 2 ; style 2-cut at apex. The genus is 

 placed near Salvia, being distinguished by the calyx 

 being only shortly 2-lipped, not hairy in the throat and 

 the connective of the anthers continuous with the fila- 

 ment and indicated only by a slender reflexed tooth.
