It was not an affair of greenhouses, like most of such places they had seen; for they were superfluous in the Torrid Zone, and all the plants grew in the open air. The ladies and most of the gentlemen were greatly interested in the plants and flowers, and the whole forenoon was agreeably passed in viewing them. Uncle Moses insisted that the baobab and the Indian banyan were literally the "biggest things" there; for the trunk of the former was ten feet in diameter, while the latter covered half a square mile of ground. The latter had been considerably damaged by a cyclone. At the end of a week in Calcutta, every day of which had been occupied to the pleasure and instruction of the tourists, Captain Ringgold insisted that they must remain no longer. It was the middle of March, and the hot weather was coming on, and the company must return to the Guardian-Mother on the following morning. It was not an unpleasant announcement, as they had all become greatly attached to the steamer, for they had always been exceedingly happy on board of her. "It is time for me to settle up our accounts, Lord Tremlyn," said the commander, as they were seated on the veranda after the intended departure had been announced. "That time has not come, Captain Ringgold; and it never will come," replied his lordship very decidedly. "I thought we had disposed of that question once for all at Bombay. You and your party have been our guests from the moment we landed. Sir Modava and I have done our best, in the time allotted to us, to make you acquainted with India, and to make the time pass pleasantly with you. As far as we had influence, we have used it to promote the objects of your visit." "You have done a hundred times more than we had any right to expect, and certainly we should not have asked for what you have given us; but it seems to be no more than right that we should pay our own expenses, and we shall be just as grateful to you for the vast service you have rendered us." "What we have done does not extinguish a tithe of our obligations to you and your ship's company. Any money allusion grieves me, and the very thought of being paid almost breaks the heart of Sir Modava. I beg you not to allude to the matter again. Now, my dear Captain Ringgold," continued his lordship, taking what looked like a picture-frame from a table near him, "I ask the privilege of presenting to you this testimonial of the gratitude of the three cabin survivors of the wreck of the Travancore, which I will ask you to hang up in the cabin of the Guardian-Mother."
