COW AND MACHINE.

" IMPORTANT MILKING ESPEFJ- • SIKKTS.- - Every dairying country in the world will bo interested in the experiments cecontly made in Denmark by N. 0. Hof-uian-Bang, of Copenhagen,, in -hand and Jimchiiifc milking during,•thosea&'fis 1907-8 and 191)8-9. Four uniform lots of 10 cows and 4 heifers each were in.the first, season's experiments, 'when' two of ,tho lota, wero tpilk'ed by machine and two by jgqd during an experimental, period of about • 3} months. Une of,the hand-milked lots .was stripped , by. hand after having been ma'cliine-milked; while this was not with the other lot. until after' forty-two days from the. beginning -of.tho .pepod when .it ;was deemed, necessary to. do' £0 on account of thprtlecrqa'so iflvtho milk .yield..CL.the-cbws.V'lrivthV-second season's i'lofs! ijfr fcr(ii'teen head each were t,\Vo*v ( of aged cows and, tiro of heifersj-one df -eaeh of these was milked by hand and the. other by. machine. : ,
