268 Select Plants for Industrial Culture and 



Capensis as one of the most brilliant of autumnaFflowering shrubs, 

 though ornamental only. 



Jacksonia cupulifera, Meissner. 



West- Australia. It might prove an advantage, to disseminate this 



small tree in arid desert-regions, as horses and cattle relish the foliage 

 amazingly. Several other Jacksonias share the local renown, which 



this congener of theirs has acquired from its utility as a pasture-bush, 



notably so the tall-shrubby J. scoparia of South-Eastern Australia ; 



it would, therefore, be worth while to disseminate these kinds of 



plants in apt localities. 



Jasminum grandiflorum, Linn.* 



From India to Japan. Flowers white. Extensively cultivated in 

 South-Europe. It is planted in rows 3 feet apart. Leek, tuberoses 

 and similar plants are used, to occupy the spare-ground for the first 

 year ; 1,000 plants in the second year after grafting produce 50 kilos 

 (about 1 cwt.) of flowers in rich soil. Ten thousand Ibs., can be 

 produced on a hectare (nearly 2J acres) ; these under very favorable 

 circumstances will realize a profit of 230 per annum. Dr. Piesse 

 records, that in very recent times at Grasse, Cannes and the adjoining 

 villages about 100,000 Ibs. of Jasmin-flowers were gathered annually 

 for perfumery-purposes, the price there being about Is. a Ib. Accord- 

 ing to the " Revue des Sciences Naturelles Appliquees " of May 

 1891 p. 720, the quantity seems to have risen to fully 300,000 Ibs., 

 gathered from the middle of May to the end of June. The plants 

 must be guarded against frost and exposure to wind [Deherain] . 

 May sometimes be attacked by Uromyces Cunninghami (Barclay). 

 In France this jasmin is generally grafted on J. officinale. The 

 bushes are richly manured and well watered. Ordinary cleft-grafting 

 is practised, the stock being headed down to near the ground. A 

 good workman and assistant will graft about 1,000 plants in a day. 

 The delicate scent is withdrawn, either by fixed oil or fat through 

 alcohol, if not required by itself, or it may be drawn over along with 

 oil of orange-peel. The pecuniary yield obtainable from Jasmin- 

 cultivation seems vastly overrated, even if inexpensive labour could 

 be procured. The concrete oil is an article of commerce. Messrs. 

 Blogg prepare it in the following superior and expeditious manner 

 here : Fresh flowers without stalks are macerated for some few 

 minutes in deodorized methyl-chloride ; the liquid is then allowed to 

 run off into a closed receiver for subsequent distillation ; this macera- 

 tion proceeds till all scent is withdrawn by additional methyl ; the 

 distillation is effected at a temperature of only about 86 F.; this 

 volatises the methyl-chloride, which when thus regained is used for 

 treatment of other lots of flowers. The concrete oil, as containing 

 the perfuming principle in a waxy or fatty nature, remains behind 

 after the evaporation of the methyl, and is worth about 30 shillings 

 an ounce. A small quantity of this solid substance suffices for pre- 

 paring a good deal of the " essence " ordinarily in use.
