The mistresses of American families, whether they like it or not, have the duties of missionaries imposed upon them by that class from which our supply of domestic servants is drawn. They may as well accept the position cheerfully, and, as one raw, untrained hand after another passes through their family, and is instructed by them in the mysteries of good house-keeping, comfort themselves with the reflection that they are doing something to form good wives and mothers for the republic. The complaints made of Irish girls are numerous and loud; the failings of green Erin, alas! are but too open and manifest; yet, in arrest of judgment, let us move this consideration: let us imagine our own daughters between the ages of sixteen and twenty-four, untaught and inexperienced in domestic affairs as they commonly are, shipped to a foreign shore to seek service in families. It may be questioned whether, as a whole, they would do much better. The girls that fill our families and do our house-work are often of the age of our own daughters, standing for themselves, without mothers to guide them, in a foreign country, not only bravely supporting themselves, but sending home in every ship remittances to impoverished friends left behind. If our daughters did as much for us, should we not be proud of their energy and heroism? When we go into the houses of our country, we find a majority of well-kept, well-ordered, and even elegant establishments, where the only hands employed are those of the daughters of Erin. True, American women have been their instructors, and many a weary hour of care have they had in the discharge of this office; but the result on the whole is beautiful and good, and the end of it, doubtless, will be peace. Instead, then, of complaining that we can not have our own peculiar advantages and those of other nations too, or imagining how much better off we should be if things were different from what they are, it is much wiser and more Christian-like to strive cheerfully to conform to actual circumstances; and, after remedying all that we can control, patiently to submit to what is beyond our power. If domestics are found to be incompetent, unstable, and unconfirmed to their station, it is Perfect Wisdom which appoints these trials to teach us patience, fortitude, and self-control; and if the discipline is met in a proper spirit, it will prove a blessing rather than an evil. But to judge correctly in regard to some of the evils involved in the state of domestic service in this country, we should endeavor to conceive ourselves placed in the situation of those of whom complaint is made, that we may not expect from them any more than it would seem right should be exacted from us in similar circumstances.
