188 Select Plants for Industrial Culture 



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 labor could be produced. 



Jasminum odoratissimum, Linn<L 



Madeira. Shrubby like the rest. Flowers yellow. Used like the 

 foregoing and following for perfumery. This may be prepared by 

 spreading the flowers upon wool or cotton slightly saturated with olive 

 oil or other fixed oil, and covering them with other layers so prepared. 

 The flowers are renewed from time to time until the oil is thoroughly 

 pervaded by the scent, when the latter is withdrawn by alcohol. 

 Other modes of extracting the oil seem feasible. 



Jasminum officinale, Linn<$. 



From the Caucasus to China. Flowers white. This is the 

 principal species cultivated in South-Europe for its scent. In Cannes 

 and Nice about 180,000 Ibs. of jasmin-flowers are produced annually 

 for distillation (Regel). By Simmonnet's process the essence of 

 jasmin is solidified as jasminin. 



Jasminum Sambac, Aiton. 



From India to Japan. It has the richest perfume of all. The 

 bush attains a height of 20 feet, and is almost climbing. The 

 flowers are white, and must be collected in the evening before expan- 

 sion. The relative value of many other species of jasmin, nearly all 

 from the warmest parts of Asia, seems in no instance to have been 

 ascertained, so far as their oils or scents are concerned. The Austra- 

 lian species are .also deliciously fragrant, amongst which J. lineare, 

 Br., occurs in Victorian deserts; while also J. didymum, Forst., J. 

 racemosum, F. v. M., J. simplicifolium, Forst., J. calcarenm, F. v. 

 M. and J. suavissimum, LindL, reach extra-tropical latitudes. 



Jubsea spectabilis, Humboldt. 



The tall and stout Coquito-Palm of Chili, hardy still in Yaldivia. 

 Adapted for mild extra-tropical latitudes. A kind, of treacle is 

 obtained from the sap of this palm. A good tree will give 90 gallons 

 of mellaginous sap (C. Darwin). The small kernels are edible. Stem 

 reaching a height of 60 feet, turgid towards the middle; leaves 

 sometimes 10 feet long. Has endured at Montpellier a winter cold ot 

 + 10 F. (Osw. de Kerchove de Denterghem). Jubaea Torallyi 

 ascends the Andes to 8,500 feet. First introduced into the colony of 

 Victoria by the writer of this work. 



Juglans cinerea, Linn.* 



The Butternut-tree of Eastern Xorth- Am erica. About 50 feet 

 high; stem-diameter to 4 feet. Growth of comparative celerity; 

 admits of transplantation readily. Likes rocky places in rich 

 forests, but is also content with poor soil. Wood lighter than that of 

 the black walnut, durable and free from attacks of insects. It is
