His brief residence on the south-sea island had taught him, by painful experience, that he _was_ capable of existing without at least two of his three B's--bread and beer. He had suffered somewhat from the change of diet; and now that his third B was thus suddenly, unexpectedly, and hopelessly wrenched from him, he sat himself down on the beach beside Cuffy, and gazed out to sea in absolute despair. We must guard the reader at this point from supposing that John Jarwin had ever been what is called an intemperate man. He was one of those honest, straightforward tars who do their duty like men, and who, although extremely fond of their pipe and their glass of grog, never lower themselves below the level of the brutes by getting drunk. At the same time, we feel constrained to add that Jarwin acted entirely from impulse and kindly feeling. He had little to do with principle, and did not draw towards those who professed to be thus guided. He was wont to say that they "was troublesome fellers, always shovin' in their oars when they weren't wanted to, an' settin' themselves up for better than everybody else." Had one of those troublesome fellows presented John Jarwin with a pound of tobacco in his forlorn circumstances, at that time he would probably have slapped him on the shoulder, and called him one of the best fellows under the sun! "Cuffy, my friend," exclaimed Jarwin at last, with an explosive sigh, "all the baccy's gone, so we'll have to smoke sea-weed for the futur'." The terrier said "Bow-wow" to this, cocked its ears, and looked earnest, as if waiting for more. "Come along," exclaimed the man, overturning his dog as he leaped up, "we'll go home and have summat to eat." Jarwin had erected a rude hut, composed of boughs and turf, near the fountain where he had first landed. It was the home to which he referred. At first he had devoted himself entirely to the erection of this shelter, and to collecting various roots and fruits and shell-fish for food, intending to delay the examination of the island until his strength should be sufficiently restored to enable him to scale the heights without more than ordinary fatigue. He had been so far recruited as to have fixed for his expedition the day following that on which he sustained his irreparable loss.
