FARM AND DAIRY.

CLEAN STRU'I'INC

Every dairy farmer knows (snvs an exchange) that 'the last drawn'nrlk of a cow is much richer than the oilier milk: hut why this in so often disputed. This is'tko reason: A cow'.- udder is composed of a solid mass uf glandular substance, npparently made up of very small no Inks or inu«i'f, so a., to separate the whole into cells or div sions.

The udder is divided inio two puds by a membrane from the front, to making two separate ami distinct halves. The halves are not divided, and yet the front and hack parts are d.stinct from e.ieh other, each quuWer being .nne.U,t W ith the feat which belongs to it by (he small cells or divisions itn.l small pipes or ducts ieadin" from them to the teat.

The upper part of the udder is made up wholly of fat, the lower part has very little fat in it. Consequently, with this structure, the udder cannot, ns many have thought, he a s lnplu reservoir of mid;, in which the cream can ri-e to the lop as it accumulates in the udder. The udder, in fact, can hold very little milk. in the examination of an udder hs' dissection the combined spaces or duct's in h are found to be iu,ullie out to hold half a pint of milk, but the milk is held as by a sponge of elo-e texture all through' the glands of the udder, and in the. small cells, wli cb thus keep the milk as if thousands of sm.ili b adders, all holding milk, were gathered into another and much larger bladder. In an culmination of fh.s k.n.l ah the milk found did not measure a pint; . and this udder was taken from a cow giving several quails at a m iking jnsl before being slaughtered. The milk, therefore, is produced in the udder as the. milking proceeds, anil the cow may prevent the How of m Ik by repress.ng this action. The giving ojf the milk is a voluntary act of the co\v,and a> she lots dowi the milk (lows from these cells iiuo the pa-sage leading into the teats. Necessarily the milk from „he upper pint of the udder can only conic down last; aim the glandular sub-slunc:! in thi. p trl of the udHcr being mostly fat, the milk is made up largely of fat, which is mingled with the serum o! milky lluiil that escapes from {he gland- I),. a change of olio substance into milk.
