BOTANICAL SOCIETY OF CANADA.

I would recommend too that the country within our boundary about Lakes 
Ontario and Superior, and our most south-western boundary be carefully explored. 
The Americans have sent me some interesting plants from their side the boundary 
very recently, especially one or two good Ferns from Lake Superior, 
The Cryptogamic plants generally of British North America, would well repay 
a careful search for them, and in all the orders. No doubt that they are numerous 
and beautiful ; — but unless the number was tolerably complete it would be better 
to omit them. 
I do not know if any Botanist accompanied the late important expedition to 
the Red River Settlement, and to the plains towards the Rocky Mountains, which 
was sent out by the Canadian Government. If so, probably some good and even 
new species were found. Much cannot be expected from a plain country, which 
has been so well ransacked by Drummond, Richardson, Douglas, Hector, Palliser, 
and, above all, Bourgeau. The collections of the latter are very fine. I do not 
know what mountains you have in Canada proper, of such height as to change 
the nature of the vegetation as you ascend. Such elevations always produce good 
plants, especially Cryptogams. 
I am. Sir, 
Your faithful and obedient servant,

On the motion of Judge Logic, of Hamilton, seconded by Andrew Drummond, 
Esq., Manager of the Montreal Bank, the Society's thanks were voted to Sir William 
Hooker, and the Secretary was requested to communicate to him the desire of the 
Society, to aid by the personal exertions of the members, and in every other pos- 
sible way, in forwarding the important object of a Canadian Flora. 
ON THE ASCLEPIAS INCARNATA, L., AS A FIBRE PRODUCING PLANT. 
By Alexander Logie. 
At the present time, when so much difficulty is felt in obtaining fibrous mate- 
rials in sufficient quantity to satisfy the requirements of modern civilization, and 
particularly to supply the constantly increasing demand for materials suitable for 
the manufacture of paper, it may not be out of place to direct the attention of the 
members of this Society to one of our native plants, which possesses a fibre of great 
strength and beauty, apparently well adapted not only to be employed in the manu- 
facture of paper, but also of textile fabrics of various kinds.
