HOMAS DRUMMOND? was born about 1780. He is known to 
have been a native of Scotland, but the exact place of his birth is 
unknown, as is also his early training and education. He was a brother 
of James Drummond, the Australian botanical explorer, and is known to 
have succeeded George Don in the nursery at Forfar. In 1825-6—7 he 
accompanied the Second Overland Arctic Expedition, led by Sir John 
Franklin, as assistant to Dr. Richardson, who was the naturalist of the 
expedition. In Canada Drummond explored very extensively, even into 
the Rocky Mountains and on the Mackenzie River where the main part 
of the expedition did most of its work. Upon the completion of the 
journey he returned to England, and from 1828 to 1829 he was curator 
of the Belfast Botanical Garden. Soon after his return to England he 
published a work upon the American mosses, which was chiefly the re- 
sult of his collections made in Canada. He again sailed for New York 
under the patronage of Drs. Hooker and Graham, for the purpose of 
exploring the southern and western United States. Beginning his tour 
at New York City in the spring of 1831, he went to Philadelphia, 
visited Bartram’s garden, thence to Baltimore, Washington, and to 
Wheeling on foot. At the last-named place he embarked for St. Louis, 
descending the Ohio River and coming up the Mississippi by boat. It 
was his original intention to join some fur-trading expedition to the far 
western country, but he arrived in St. Louis too late for this. He ac- 
cordingly remained in St. Louis and collected in the vicinity until the 
next winter. He lost considerable time by sickness, but in January he 
sent a collection of several hundred species of phanerogams and a con- 
siderable collection of mosses and hepatics to Hooker at Kew. Hooker
