seed store in New York, it was arranged that Inglis 

 should grow seeds also. This was in 1803; and in that 

 year Inglis, as an experiment, had grown a lot of seeds. 

 Thorburn bought these seeds for $1.5; and thus arose 

 the first regular seed store in New York, and one of the 

 first in the United States. 



The seeds and plants continued to sell, and Tliorburn 

 was obliged to import seeds. In 1805 or 180tl he ob- 

 tained a catalogue of William Malcolm & Co., London, 

 the first plant catalogue he had ever seen, and he then 

 published one of his own. This led to more pretentious 

 writing, and "The Gentleman and Gardener's Kalendar" 

 was the first outcome. The third edition of this, in 1821, 

 by "Grant Thorburn, Seedsman and Florist," contains 

 tlie advertisement of "G. Thorburn & Son," dealers in 

 seeds, implements and i-ural books. 



Grant Thorburn was a prolific writer for the current 

 press on a variety of topics, under the iiom de plume of 

 Laurie Todd. He was a unique character, and his his- 

 tory,— "mixed with much fiction," as he himself says,— 

 was the basis of John Gait's tale in three volumes 

 (London, 1830) of "Lawrie Todd, or Settlers in the 

 Woods." Thorburn left a most interesting autobio- 

 graphy, which was published in New York in 1852. He 

 died in New Haven, Conn., January 21, 186.S, at the age 

 of 90. The portrait in Plate XLI is reproduced from 

 his autobiography. L, H. B.

 care. They are mostly of elegant form and habit. A 

 good specimen is shown in Pig. 2499.
