AN INTERESTING POINT.

THE PERSONAL EQUATION IN MILKINU;. i ■ Tho fallowing experience- recounted by Mr. 0. E. Heed, of Kansas State Agricul- , tural College, will doubtless be reiia with -.interest by dairymen. • A heavy-produc-ins Holsteiu. cow in the dairy herd at ' tlio Kansas State Agricultural College . freshened early', in 'December, land was milked by man No, 1, v This man had milked her for several. weeks, . when he left .-for a vacation. '■■ Man No. 2 took Charge of the milking. The cow responded ' to his milking, and gave as much as 81.*t pounds of milk' per day. Her highest day previous to this was 70 pounds. Jlan ■ No. 1 returned after a short time, and again took charge of the milking. The cow. began to decline in milk production at once,, and'fell, .to as, low; as (&2 pounds of milk per *day. .After, six days man ■No. !i,was given charge of,-tlio.'milking, and the cow began to make an'.'increase : in the flow of milk. The. following shows the results obtained:—. ■

Average of six. days by man ' No. 2, 76.111b...0f milk.- - '.- Average of, six days' by man Ko. 1, 61881b. of milk. ... Average of six, days by _ man No.; 2, 59.5 pounds of milk. .\ Evidently man No. ! could not. get, the cow to respond to ' lifs milking ..as' well as man No. 2. Fo'rUin average-of six. days the cow.-gave 11.23 .'pounds less milk peivday when she was milked by man. No. 1. When man N0..2 took,charge of her she.sihowed an increase for the next, six days of 4.62 pounds of imilk per-day.. Man No. 2 has been milking'the cow for two months, and the production has never gotten as low as it did during the six days: in which man; No.. 1 milked: her.' Tho influence .of the changing of these milkers is really greater than. the figures' given above show. A;moj'o accurate_way, of ; ishowing: the, difference in' yields? obtained would be to eliminate; a' twordays' production immediately after the change. I'or instance,'"by'.' eliminating the!two days, -and' taking an average of ..the. last, four days' milking inVeach period, we have the following:—'

Average for. four days by man No. 2, ,76.8.pounds of milk. '■■>'• Average for four days by man No. 1, 03.1 pounds of milk. , , - Average for four -days-by man' No. 2, 70.6 pounds of milk. . ' -- , The four days' milking by man No 4 '.2'. would be'; the last; four days he ■ milked her'before man No. 1' took-charged Two days w.ere eliminated .after maii";Np. 1' took charge, and thel next four day?.-gives the average 0f',63.4V .The-average of '7616 pounds was made by/eliminating, thetwo days after maii No. 2 again 1 took charge, iind making an average of the next four days. , The weather conditions ajid.tha; feeding were" approximately.'.'the same throughout the experiment. ' The;'above results show the importance of' changing ■ milkers until each milker ishandling tlieoows;which'Will < respond'/ to'' his' "milking/ tl'his is -especially-■ lmpbrtant' in- '-large* nerds, where 1 tli-ero • are several milkers.' The evidence' was at - hand' to' show' that man No. J. is an efficient milker,; and he -it-ns, able to get, more milk out. of some other cows in (lie. herd "than" was" maii No.-2;'
