MEMOIR OF DAVID DOUGLAS 297 



says " I have made arrangements with Captain Charlton our Consul to aid me 

 should I return there, which I shall earnestly endeavour to do." Accordingly we 

 find him leaving the Columbia River on October 18, : 1833, and arriving at Hawaii 

 in the Sandwich Islands on January 2, 1834. On the 7th he started to ascend 

 Mouna Roa, the great volcano of the Sandwich Islands, of which he sent home an 

 account to his brother Mr. John Douglas, which will be found in Appendix II, 

 pp. 298-317. This was the last letter or communication received from David 

 Douglas. All that is known further is contained in Appendix III, pp. 318323 : 

 a very sad end to the life of one of our greatest and most successful exploring 

 Botanists, to whom the whole world is deeply indebted.
