Our readers may probably have from time to time read allusions to 'Sailors' Homes,' without precisely understanding the nature of these institutions. They are based on the fact that sailors, as a class, are little better than children when ashore, and require to be providently cared for, to save them from imposition and misery. The seaman when afloat is so thoroughly accustomed to obey orders, and to be directed and instructed in everything, that he never thinks for himself, and never acquires the least forethought or capability of guiding himself in any position apart from the active duties of his profession; consequently, from time out of mind, he has been especially doomed to be victimised on the land. No sooner has he been paid off after a voyage, than he is--at least at all the great ports--beset with 'crimps,' 'runners,' and other land-sharks, who entice him to low public-houses and lodging-houses, where he is plundered with such extraordinary dispatch, that he frequently loses the results of many months of toil in a few days, or even a few hours. Of all men, seamen have pre-eminently a claim on public sympathy and protection; no class needs the latter more, and, strange to say, no class has, until a comparatively recent period, received it less. In the words of Thomas Clarkson: 'The grievances of mercantile seamen are a national and crying evil;' and when we reflect on their importance, both as regards commerce and war, it will be acknowledged that it is a national duty to do all that is possible to protect them while ashore, and to ameliorate and improve their lot in every practical way. But this, like many other national duties, has been left to the voluntary exertions of a few practical philanthropists. In the words of Mr Sheriff Alison (now Sir A. Alison), when addressing a meeting at Glasgow, with the view of founding a 'Home' there: 'The seamen are placed in very peculiar circumstances--their virtues are exhibited at sea, and their vices are exhibited on shore. The community is benefited by the former, and they, the sailors, are the victims of the latter. It is therefore more incumbent on those who are enriched by their industry, and protected by their valour, to prevent their falling into those vices to which unhappily so many of them are addicted. As had been so well stated, they could do nothing to improve the character of the seaman without at the same time benefiting all classes of the community.'
