so, what is the smallest quantity of potash, a very expensive 

 article, vi^hich will answer the purpose. M. Quenard's direction 

 for making the lie is, to mix, with a certain quantity of water, five 

 parts of ashes with three parts of soot, and, after stirring them 

 well, to add one part of quicklime just slaked, to ten of soot 

 and ashes mixed, i. e. 125 ashes, 75 soot, and 20 lime. The mix- 

 ture is to be often stirred during twenty-four hours, and is said 

 to be then in a state of powerful efficacy, and it is recommended 

 to keep a portion of the old liquor to use, like yeast in brewing, 

 to promote the fermentation of futui^e mixtures. It is evident 

 that experiments to ascertain the nature and value of the asserted 

 fermentation will be most easily made by a lie, but that the pro- 

 cess for horticultural or agricultural purposes, if beneficial, would 

 be most easily effected by heaping the ingredients in layers. On 

 my return to the country, I shall make some experiments as to 

 the fermentation of lime by the addition of soot and potash, but 

 in the meantime it seems to me desirable that you should call 

 the attention of the public to the subject, in the Gardene7-''s 

 Magazitie, or in some other of your valuable publications.
