the world, and Mr. Frazer, who had previously explored a 

 part of our country, during three several tours, made his 

 last voyage in company with his eldest son. He sent home 

 in all upwards of seventy-five new species, numbering 

 thousands of specimens, part of which were purchased by 

 the Empress Catherine of Eussia. 



Mr. John Lyon, about the same period, introduced 

 American plants on a gigantic scale. In 1805 he returned, 

 after an absence of three years, with the greatest collection 

 of trees and shrubs ever brought to England at one time. 

 His catalogue filled thirty-four closely-printed pages, and 

 the sale occupied four days. In 1812 he again took to 

 England a similar quantity. In 1823 the London Horti- 

 cultural Society sent Mr. David Douglas to the Northwest 

 Coast, and the plants and trees he introduced — from a 

 newly-explored region — were greater than those of any 

 other botanist. Only a few of the trees, however, are 

 found hardy in our northern climate ; but among the 

 shrubs was the beautiful Mahonia, with its deep-green 

 glossy leaves, exquisitely tinted and bronzed on the ap- 

 proach of winter. The flowers he discovered are now the 

 most common and decorative ornaments of every parterre. 

 The whole number of species of trees and plants introduced 

 into England from 1800 to 1835 was six hundred and 

 ninety-nine, and of these five hundred and twenty-eight 

 were natives of North America ! How long before our 

 planters will cease to introduce foreign trees to the neglect 

 of our own, the pride and boast of every English garden ?
