Having remained a few days with his favorite Highland corps, he returned to St. Simons, where he found Tomo Chichi, Toonahowi, and a party of Indians consisting of about forty men, "all chosen warriors and good hunters;" who had come down to show him what Islands they claimed as having belonged to their nation, but which had been ceded to him by treaty, and to which they would now give him the formal possession. To accomplish this, the General fitted out an expedition, to take them with him in the two ten-oared boats, with Major Horton, Mr. Tanner, and some other gentlemen as his escort; and a sufficient number of able hands both as boat-men and soldiers, and to man the periagua,[1] with Highlanders under the command of Captain Hugh Mackay. He the more readily engaged in this excursion from an impatient desire to gain intelligence of Major Richard, and the deputation to St. Augustine. [Footnote 1: The Periagua is a long flat-bottomed boat, carrying from twenty to thirty-five tons. It is constructed with a forecastle and a cabin; but the rest is open, and there is no deck. It has two masts, which the sailors can strike, and sails like those of schooners. It is rowed, generally, with two oars only.] They set out on the 18th of March. On the first day they visited an island in the mouth of the Alatamaha, sixteen miles long, and from one to five broad; opposite the entrance of the great Latilla river. By the Indians it was called WISSOE, _Sassafras_; but the Spaniards had named it _San Pedro_. Toonahowi, pulling out a watch that had been given him by his Royal Highness the Duke of Cumberland, desired that it should bear his name; saying, "He gave me this watch, that we might know how time went; and we will remember _him_ while time goes; and this place must have his name, that others may be reminded of him." The General left Captain Mackay and the Highlanders here, with directions to build a fort on the high ground, commanding the passes of the river; which, at their desire, should be called St. Andrews. On the south-east part of this island another strong fort was afterwards built, called Fort William, which commanded Amelia Sound, and the inland passage from St. Augustine. On their excursion, the next day, they passed the Clogothea, an arm of the Alatamaha, and went ashore on a delightful island, about thirteen miles long, and two broad, with orange trees, myrtles and vines growing on it. The wild-grape vines here, as on the borders of the Savannah, grow to the very top of the trees, and hang from limb to limb in festoons, as if trimmed and twined by art.[1] The name of this island, _Santa Maria_, they changed to AMELIA, in honor of her Royal Highness.
