ANNALS OF THE 
tered at Shanghai of the enormous quantity of 55,000 catties, from the 11th Nov., 
1858, to 30th June, 1859. This root is found in abundance in the western part of 
Minnesota, principally in the woods on oak ridges, and there are persons who make 
large sums by collecting it, and selling at St. Paul for one dollar per lb. ; by send- 
ing it to New York, they get a much higher price. Now, as this root is so valu- 
able, and as the climate and soil in some parts of Canada resemble that of Minne- 
sota, I wish merely to mention the possibility of cultivating it in Canada. Hither- 
to the market has been supplied by indigenous growth, and the consequent disap- 
pearance of the plant in many parts of Canada and the States suggests the propri- 
ety of adopting measures by which its production may be increased by artificial 
means. 
The following is a list of the specimens collected, with their localities. Most 
of the species were determined or confirmed by Professor Lawson.
