The truth is, the idea of mutton of this age being especially excellent, is founded on a prejudice, arising, probably, from this circumstance: before winter food was discovered, which could maintain the condition of stock which had been acquired in summer, sheep lost much of their summer condition in winter, and, of course, an oscillation of condition occurred, year after year, until they attained the age of five years; when their teeth beginning to fail, would cause them to lose their condition the more rapidly. Hence, it was expedient to slaughter them at not exceeding five years of age; and, no doubt, mutton would be high-flavored at that age, that had been exclusively fed on natural pasture and natural hay. Such treatment of sheep cannot, however, be justified on the principles of modern practice; because both reason and taste concur in mutton being at its best whenever sheep attain their perfect state of growth and condition, not their largest and heaviest; and as one breed attains its perfect state at an earlier age than another, its mutton attains its best before another breed attains what is its best state, although its sheep may be older; but taste alone prefers one kind of mutton to another, even when both are in their best state, from some peculiar property. The cry for five-year-old mutton is thus based on very untenable grounds; the truth being that well-fed and fatted mutton is never better than when it gets its full growth in its second year; and the farmer cannot afford to keep it longer, unless the wool would pay for the keep, since we have not the epicures and men of wealth who would pay the butcher the extra price, which he must have, to enable him to pay a remunerating price to the grazier for keeping his sheep two or three years over. All writers on diet agree in describing mutton as the most valuable of the articles of human food. Pork may be more stimulating, beef perhaps more nutritious, when the digestive powers are strong; but, while there is in mutton sufficient nutriment, there is also that degree of consistency and readiness of assimilation which renders it most congenial to the human stomach, most easy of digestion, and most promotive of human health. Of it, almost alone, can it be said that it is our food in sickness, as well as in health; its broth is the first thing, generally, that an invalid is permitted to taste, the first thing that he relishes, and is a natural preparation for his return to his natural aliment. In the same circumstances, it appears that fresh mutton, broiled or boiled, requires three hours for digestion; fresh mutton, roasted, three and one-fourth hours; and mutton-suet, boiled, four and one-half hours.
