The seed of Zizania aquatica in a vegetating state from America 

 was long a desideratum among the botanists of this country ; for 

 although seeds were received here at different times, yet none of 

 them grew. At last Dr. Nooth, by the desire of Sir Joseph Banks, 

 sent them from the lakes of Canada, put up in jars of water. As 

 soon as they arrived they were sown in a proper situation, where 

 they came up in a few days, and the plants ripened their seeds 

 extremely well in the autumn. In a pond at Spring-Grove Sir 

 Joseph Banks has a great quantity of this plant, growing annu- 

 ally, ripening its seeds, and sowing itself round the edges ; and 

 I am persuaded that it might be sown with some advantage 

 where no other grain will grow, in many shallow pieces of water 

 in Great Britain and Ireland, especially in the latter country, 

 where I have seen several extensive lakes which appear well suited 

 for the purpose. It grows in great abundance in the lakes of 



Canada ;
