"Pardon, but you are Captain Flanagan of the yacht _Laura_?" "Yessir," patiently. "But the owner never lets anybody aboard he don't know, sir." "I do not desire to come aboard, my Captain. What I wish to know is if his excellency the admiral is at home." "His excellency" rather confounded the captain for a moment; but he came about without "takin' more'n a bucketful," as he afterward expressed it to Halloran the engineer. "I knew right then he wus a furriner; I know 'em. They ain't no excellencies in th' navy. But I tells him that the commodore was snug in his berth up yonder, and with that he looks to me like I wus a lady. I've seen him in Swan's at night readin'; allus chasin' butterflies when he sees 'em in the street." And the captain rounded out this period by touching his forehead as a subtle hint that in his opinion the foreigner carried no ballast. In the intervening time the subject of this light suggestion was climbing the hill with that tireless resiliant step of one born to mountains. No task appeared visibly to weary this man. Small as he was, his bones were as strong and his muscles as stringy as a wolf's. If the butterfly was worth while he would follow till it fell to his net or daylight withdrew its support. Never he lost patience, never his smile faltered, never his mild spectacled eyes wavered. He was a savant by nature; he was a secret agent by choice. Who knows anything about rare butterflies appreciates the peril of the pursuit; one never picks the going and often stumbles. He was a hunter of butterflies by nature; but he possessed a something more than a mere smattering of other odd crafts. He was familiar with precious gems, marbles he knew and cameos; he could point out the weakness in a drawing, the false effort in a symphony; he was something of mutual interest to every man and woman he met. So it fell out very well that Admiral Killigrew was fond of butterflies. Still, he should have been equally glad to know that the sailor's hobby inclined toward the exploits of pirates. M. Ferraud was a modest man. That his exquisite brochure on lepidopterous insects was in nearly all the public libraries of the world only gratified, but added nothing to his vanity. As it oftentimes happens to a man whose mind is occupied with other things, the admiral, who received M. Ferraud in the library, saw nothing in the name to kindle his recollection. He bade the savant to be seated while he read the letter of introduction which had been written by the secretary of the navy. "MY DEAR KILLIGREW: "This will introduce to you Monsieur Ferraud, of the butterfly fame. He has learned of the success of your efforts in the West Indies and South America and is eager to see your collection. Do what you can for him. I know you will, for you certainly must have his book. I myself do not know a butterfly from a June-bug, but it will be a pleasure to bring you two together."
