Returning to Malta, he passed through Sicily, and ascended Mount Etna.

In 1818 he left England for the United States, and spent nearly two years in rambling through that country.

Thence he proceeded to Brazil and Chile, returning to Rio de Janeiro, where he practised his art until the commencement of 1824.

Having received letters of introduction to Lord Amherst, who had left England to undertake the government of India, Mr.Earle left Rio for the Cape of Good Hope, intending to take his passage thence to Calcutta.
On the voyage to the Cape the vessel by which he was a passenger touched at Tristan d'Acunha, and was driven off that island in a gale while Mr.
Earle was ashore, leaving him stranded in that desolate land, where he remained for six months, when he was rescued by a passing ship, the "Admiral Cockburn," bound for Van Diemen's Land, whence he visited New South Wales and New Zealand, returning again to Sydney.

In pursuance of his original resolution to visit India, he left Sydney in "The Rainbow," touching at the Caroline Islands, Manilla, and Singapore.
