Doubtless, through various exigences, large numbers of women betake themselves to professional employment of some kind. They become domestic servants, governesses, teachers, dressmakers, shop-assistants, and so on. While still young they work in factories. But we repeat that whatever they do in these several respects is done on the principle of a temporary make-shift; the predominant hope they indulge being that they will some day settle down as the happy and respected mother of a family. In this candid view of the matter it is hardly to be expected that women--taking them all in all--will ever make that resolutely persevering effort to attain the proficiency in a profession which is universally aimed at by men. To expect anything of the kind, is to hope for more than human nature can justify. In the notification which has been made respecting wood-engraving, it is specified that young ladies must make up their minds to study six hours a day for six years. Of the propriety of this obligation, we have no doubt. What concerns us to know is, how, besides paying fees, young ladies driven to the expedient are to live in the meanwhile, and how many will persist in giving six years of assiduous diligence in learning a profession which any day may be tossed aside on marriage, the paramount object in life, being happily achieved. As far as we know, there are few or no instances of any regular trade being successfully appropriated entirely by women. Such, indeed, is not to be looked for, and, properly speaking, no blame ought to rest on females for essentially following a primarily assigned duty. We have known cases in which, from motives of benevolence, young women alone were invited to conduct a trading experiment, and they failed, not from want of skill, but want of perseverance. The members of the establishment broke away piecemeal, and went to other and more attractive pursuits. Where young men are employed along with young women in any commercial undertaking, there is less chance of disruption; and the reason why is so obvious as to need no particular explanation. No accusation can be made on this account. Celibacy is a violation of every instinct and sense of social obligation. It is often nobly submitted to as a duty by females, but the instinct is indestructible and to be respected.
