The previous chapter gave account of an immense body or herd of Sperm Whales, and there was also then given the probable cause inducing those vast aggregations.

Now, though such great bodies are at times encountered, yet, as must have been seen, even at the present day, small detached bands are occasionally observed, embracing from twenty to fifty individuals each. Such bands are known as schools. They generally are of two sorts; those composed almost entirely of females, and those mustering none but young vigorous males, or bulls as they are familiarly designated.

In cavalier attendance upon the school of females, you invariably see a male of full grown magnitude, but not old; who, upon any alarm, evinces his gallantry by falling in the rear and covering the flight of his ladies. In truth, this gentleman is a luxurious Ottoman, swimming about over the watery world, surroundingly accompanied by all the solaces and endearments of the harem. The contrast between this Ottoman and his concubines is striking; because, while he is always of the largest leviathanic proportions, the ladies, even at full growth, are not more than one-third of the bulk of an average-sized male.
