BOTANICAL INFOKMATION. 91 



substance is dissolved^ it is easy to separate the fibres, to wash them 

 and free them from all foreign substances. According to the mode of 

 preparation employed, the woolly (or fibrous) substance acquires a 

 quality more or less fine, or remains in its coarse state; in the first 

 instance it is used as wadding, in the second to stuff mattrasses. If 

 this Pine has been preferred to other of our Pines, it is on account of 

 the length of its leaves. It can be stripped of its foliage when quite 

 young, without any injury ; the operation takes place when it is still 

 green. A man can gather 2001bs. of leaves a day, 



"It was first advantageously substituted for cotton and wool in the 

 manufacture of blaukets. The hospital of Vienna bought 500, and 

 after a trial of several years, has adopted them entirely. It has been 

 remarked, among other advantages, that no kind of insects would lodge 

 in the beds, and the aromatic odour was found agreeable and beneficial. 

 These blankets have since been adopted by the Penitentiary of Vienna, 

 the Charity Hospital, and the barracks of Breslau. 



"Its cost is only one-third of that of horsehair; and the most ex- 

 perienced upholsterer, when the wool is employed in furniture, could 

 not tell the one from the other. It can be spun and woven, and resem- 

 bles the thread of hemp for strength, and it may be made into rugs and 

 horse-blankets. 



" In the preparation of this wool, an ethereal oil of a pleasant odour 

 is produced. This oil is at first green : exposed to the rays of the sun, 

 it assumes an orange-yellow tint ; replaced in the shade, it resumes its 

 former green colour; rcctifted, it becomes colourless. It differs from 

 the essence of turpentine extracted from the same tree. It has been 

 found efficient in rheumatism and gout, also as an anthelmintic in cu- 

 taneous diseases. Distilled, it is used in the preparation of lac of the 

 finest kind. It burns in lamps like olive oil, and dissolves caoutchouc 

 completely in a short time. Perfumers in Paris use it in large quan- 

 tities. 



" It is the liquid left by the decoction of the Pine-leaves, which has 

 been so beneficial in the form of bath. The bath establishment is a 



flourishing one. 



"The membranous substance obtained by filtration at the time of 



the washing of the fibres, is pressed in bricks, and dried ; it is used as 



a combustible, and produces, from the resin it contains, a quantity of 



gas sufficient for the lighting of the factory. The production of a
