That evening, Mr. Carvalho came, and I liked him better than ever. Mr. Cameron, who was a brother botanist and a nice ingenuous young Highlander, made him bring his portfolio of Jamaica ferns and flowers, the loveliest things I ever saw--dried specimens and water-colour sketches to accompany them of the plants themselves as they grew naturally. He told us all about them so enthusiastically, and of how he used to employ almost all his holidays in the mountains hunting for specimens. "I'm afraid the fellows at the office think me a dreadful muff for it," he said, "but I can't help it, it's born in me. My mother is a descendant of Sir Hans Sloane's, who lived here for several years--the founder of the British Museum, you know--and all her family have always had a taste for bush, as the negroes call it. You know, a good many mulatto people have the blood of able English families in their veins, and that accounts, I believe, for their usual high average of general intelligence." I was surprised to hear him speak so unaffectedly of his ancestry on the wrong side of the house, for most light coloured people studiously avoid any reference to their social disabilities. I liked him all the better, however, for the perfect frankness with which he said it. If only he hadn't been a brown man, now! But there, you can't get over those fundamental race prejudices. Next morning, as the Major and I were out riding, we came again across Mr. Cameron and Mr. Carvalho. Fate really seemed determined to throw us together. We were going to the Fern Walk to gather gold and silver ferns, and Mr. Carvalho was bound in the same direction, to look for some rare hill-top flowers. At the Walk we dismounted, and, while the two officers went hunting about among the bush, Mr. Carvalho and I sat for a while upon a big rock in the shade of a mountain palm. The conversation happened to come round to somewhat the same turn as it had taken the last evening. "Yes," said Mr Carvalho, in answer to a question of mine, "I do think that mulattos and quadroons are generally cleverer than the average run of white people. You see, mixture of race evidently tends to increase the total amount of brain power. There are peculiar gains of brain on the one side, and other peculiar gains, however small, on the other; and the mixture, I fancy, tends to preserve or increase both. That is why the descendants of Huguenots in England, and the descendants of Italians in France, show generally such great ability." "Then you yourself ought to be an example," I said, "for your name seems to be Spanish or Portuguese."
