China, was communicated to me fome years ago by the 

 celebrated profeffor Linnxus, of Upfal, in Sweden, He 

 advifes, that each fort of feed fhould be put up in feparate 



papers, with fine fand among them, to abforb any moifture 

 (dried, loamy or foapy earth may be tried) : Thefe papers, 

 he fays, fliould be packed clofe in cylindrical glafs, or 

 earthen veffels, and the mouths covered over with a blad- 

 der, or leather tied faft round the rims : he then directs 

 that thefe veJTels, with the feeds in them, fhould be put into 

 other veffels, which fhould be fo large, that the inner veffel 



may be covered on all fides, for the fpace of two inches, 

 with the following mixture of fults. Half common culi- 

 nary fait; the other half to confift of two parts of fait- 

 petre, and one part of fal-ammoniac, both reduced to a 

 powder, and all thoroughly mixed together, to be placed 

 about the inner veffel, rather moift than dry. This he 

 calls a refrigeratory; and fays it will keep the feeds cool, 

 and hinder putrefad;ion. Perhaps if fmall tight boxes, or 

 cafks or bottles of feeds were inclofed in caflcs full of falts, 



it might be of the fame ufe, provided the falts do not get 

 at' the feeds; and as fal-ammouiac may not be eafily met 

 with, half common fait, and the other half falt-petre, or 

 common fait alone, might anfwer the fame end. But it 

 would be very neceffary to try both methods, to know 

 whether the latter would anfwer the purpofe of the form- 

 er, as it would be attended with much lefs trouble, and 

 might prove a ufeful method to our feedfmen, in fending 



feeds from hence to thofe warm climates. 



The fmalleft feeds being very liable to lofe their vege- 

 tative power by long voyages tlirough warm climates, it 

 may be worth while to try the following experiment up- 

 on fuch kinds as we know for certain are found. Dip 

 fome fquare pieces of cotton cloth in melted wax, and 

 while it is foft and almofl cold, ftrew the furface of each 

 piece over with each fort of fmall feed, then roll them up 

 tight, and inclofe each roll in fome foft bees-wax, wrap- 

 ping up each of them in a piece of paper, with the name
