the fecond 356, and the third 600 pounds of filk. If th* 

 leaves, after ihe crop has been collected, be thrown toge- 

 ther in heaps to rot, they form an excellent manure for fu- 

 ture ufe, in regard to the preparation of the filk, little is 

 necefTary to b&faid. It may eafiiy be conceived that it will 

 be of advantage to feparate that which is long from the 

 morter part, in order that the former may be employed for 

 fpinning. The fhorter kind may be ufed for beds and for 

 hat-making. 



This plant may be employed alfo in the manufactory of 

 paper. Schmid, an ingenious paper-maker near Lunenburg, 

 has made feveral experiments with the capfules of this plant, 

 which gave the following remits : 



1 ft, From the interior white rind of the capfule, mixed 

 with one-third of rags, he obtained writing-paper pretty 

 white, of a good quality, and ftmilar to the filk paper of the 

 Chinefe. 



2d, From the external green part of the capfules a greenifh- 

 coloured paper, which, when fized, was ftronger than paper 

 made of rags: "it was almoft as clofe in its texture as parch- 

 ment, and even when unfixed did not fuffer the ink to pe- 

 netrate through it. This kind was exceedingly proper for 

 wrapping-paper. 



3d, From the ftems he obtained a paper fo like in every. 

 thing to common paper made of rags, that the difference 

 could 1'carcely be diitinguiihed.

VV E are indebted to C. Gcngembre for the interefting 

 difcovery of phofphorifed hydrogen gas. No chemift before 

 him had obferved an elaftic fluid which, like the one here 

 fpoken of, pofTeiles the finguhr property of inflaming by the 

 contact of the air alone, without requiring its temperature to 

 be raifed, or an ignited body to be prefented to it.
