As the exercise of all our faculties tends to increase their power, unless it be carried to excess, it is very important that the aged should be provided with useful employment, suited to their strength and capacity. Nothing hastens decay so fast as to remove the _stimulus_ of useful activity. It should become a study with those who have the care of the aged to interest them in some useful pursuit, and to convince them that they are in some measure actively contributing to the general welfare. In the country and in families where the larger part of the domestic labor is done without servants, it is very easy to keep up an interest in domestic industrial employments. The tending of a small garden in summer--the preparation of fuel and food, the mending of household utensils--these and many other occupations of the hands will keep alive activity and interest, in a man; while for women there are still more varied resources. There is nothing that so soon hastens decay and lends acerbity to age as giving up all business and responsibility, and every mode possible should be devised to prevent this result. As age advances, all the bodily functions move more slowly, and consequently the generation of animal heat, by the union of oxygen and carbon in the capillaries, is in smaller proportion than in the midday of life. For this reason some practices, safe for the vigorous, must be relinquished by the aged; and one of these is the use of the cold bath. It has often been the case that rheumatism has been caused by neglect of this caution. More than ordinary care should be taken to preserve animal heat in the aged, especially in the hands and the feet. In many families will be found an aged brother, or sister, or other relative who has no home, and no claim to a refuge in the family circle but that of kindred. Sometimes they are poor and homeless, for want of a faculty for self-supporting business; and sometimes they have peculiarities of person or disposition which render their society undesirable. These are cases where the pitying tenderness of the Saviour should be remembered, and for his sake patient kindness and tender care be given, and he will graciously accept it as an offering of love and duty to himself. "Inasmuch as ye have done it to the least of these my brethren, ye have done it to me." It is sometimes the case that even parents in old age have had occasion to say with the forsaken King Lear, "How sharper than a serpent's tooth it is to have a thankless child!" It is right training in early life alone that will save from this.
