To what purpose do A., B., and C., and a score of other industrious, honest, painstaking fellows, exert themselves to collect a model dairy, sparing neither time nor expense in providing themselves with perfect sets of improved appurtenances for those dairies, from rich, well-watered pastures down to good, substantial three-legged milking stools, and labor incessantly from sunrise until sundown, that their barns may be in perfect order and everything connected with the business neat and clean, in order that their material may come into the hands of the manufacturer in a perfect condition--if heedless, lazy, shiftless, dishonest, ignorant, good-for-nothing D. keeps about him a herd of sick, disconsolated racks-of-bones, to wander over his arid and desolate fields in search of food and drink in summer, or with backs humped up, hover together for shelter under the lea of a wheat-straw stack, their only food in winter, and using a kit of dairying tools, the very best article of which is an old, water-soaked, dirty wooden pail, drawing his whey from the factory in the old, rusty, time-embattled milk cans, in which it is allowed to stand until the next milking, and which, after an imperfect washing, and refilled and returned to the factory, freighted with a compound sufficiently poisoned to nullify and undo the best efforts of a hundred A., B., and C's. It may be theorizing and visionary to talk of a time when the spirit of co-operation shall have driven such fellows out of the dairying business, to betake themselves with a pick-ax and spade to the ditch, but that such a time may come ought to be the earnest prayer of every thorough-going friend of co-operation in the land. It may seem like castle building and an unprofitable waste of time to indulge in theories and construct plans by which the rivalry among factorymen may be kept within a limit sufficiently circumscribed to prevent the fear of loss of patronage from interfering with, and lowering the standard of, our cheese. It is too often the case, nowadays, that factorymen are deterred from a full and complete discharge of their duty to themselves, their patrons, and the world in general, by a fear, by no means groundless, that a bold and upright course with regard to the material brought to them will result in a damaging, if not entire loss, of their occupation.
