THE USE OF STARTERS.

AMERICAN METHOD.. 'X bulletin of the Michigan Experiment Station describes their mode of using starters;' Quart'bottles of milk are plugged with !cottori wool and sterilised by ; steam. Ono bottlo is inoculated with a puro culture of lactic-acid bacteria, and after a transfer, has been niade from'this,, on tho second' day it is used for inoculating a'large can of recently-pasteuriscd milk, .which may bo used the next day as astarter. Tho advantages of the niethod are stated as follow: — Tho starter can be kept pure for a much longer period, thus saving, one-half'or 'mqrb of the cost of pure cultures.' . r■ • The milk is - always ready for inoculation; and'tho mother starter can be transferred each day when in , the best condition,. and kept vigorous.', " In case'a starter is not . needed every day, tho mother starter can be carried along-con-veniently without the trouble'of sterilising milk. ' ' . • ' ' ' . The. station' officials' find it no great , task to sterilise the necessary bottles of milk once or twice a month, aiicl die little extra' labour, is liioro than' counterbalanced by the convenience and'sureness of the new method.
