tions, and assuming different attitudes, in order to test the 

 suitability of the proposed arrangement; and, finally, when 

 fitted to its entire satisfaction, it walks off, evidently pleased 

 with its success, and generously leaves the old shell for the 

 accommodation of any future house-hunter less corpulent than 

 itself. Rot unfrequently two hermits will meet and dispute 

 the possession of a vacant shell. Arbitration is never sought 

 in these cases. It is simply a contest between the two for 

 mastery a trial of physical power ; and, where the com- 

 batants are well matched, the conflict is generally of a fatal 

 character ; for the possession of a convenient house is con- 

 sidered of such vital importance that the one or the other is 

 determined to obtain the coveted shell, and, at all times 

 pugnacious, each is resolved to die rather than yield in- 

 gloriously to its opponent. This sea-fight often occurs. 

 The slain are not a few. Sometimes a less serious encounter 

 may be witnessed, as when mig/it exercises its too frequent 

 tyranny over riyJd. The following incident affords a good 

 illustration : Two hermits met accidentally, it may be sup- 

 posed, within the vivarium on Holy Island. The one was 

 somewhat stouter than the other; and the weaker brother, 

 appearing at first sight to possess the larger house, received 

 an immediate summons to turn out and vacate his premises. 

 The summons was disputed, a furious combat commenced, 

 and, after a variety of manoeuvres, with thrusts and counter- 

 thrusts, the stronger, with a dexterous use of the hands, 

 seized the little fellow by both his wrists, and endeavoured 

 to shake him out, despite the opposition that was offered. 

 The shells rattled against the glass wall. It was a fierce 

 engagement. At last the older hermit, coming partly out of 

 his shell, seemingly for the purpose of obtaining a better 

 purchase and a greater command of his strength, pulled, and 

 pulled, and pulled again still drawing himself farther out 

 of his shell, as if he felt that the work was desperately tough 

 until the youngster giving way, stood, unhoused, discomfited, 

 and embarrassed, to abide the good pleasure of his master.
