BUTTER EXTRACTOR.

The butter extractor, manufactured by the Extractor Company, of Stockholm, is exhibited and sold in this country by the Aylesbury Dairy Company, of London. This remarkable machine turns out butter, at the rato of a pound. fa* minute, as long as it is fed vi'.h't-resb/milk. Itls a cream separator first of all, and can be made to discharge cream or butter at the will of the operator ; who has simply to move a lever in order to elf set the difference. The butter-making* part of the machine consists of a free trundle-whoel placed ineide the drum, where it 'comes into contact with the revolving wall of cream separated from the milk. The wheel is caused by the cream to revolve very rapidly, and the agitation of the cream p*oduced hy tho wheel suffices to separate the butter globules held in suspension, which are forced out of a spout, whence thoy fall into iced brine in a granular form, very much as butter comes from a churn when it is not (as it should not be) churned into a lump. The butter is afterwards drained and dealt with in a butterworker. The Quean, and other members of the Royal family have been to see this very ingenious invention But shall churns be superseded ? I think not. In the fiist place the extractor .makes butter from perfectly fresh in ilk, or rather from the cream immediately after its extraction from the fresh mik; whereas the best of butter, in my opinion, can be made only from ripened cream. Then we donotj-et know whether the uew.maohine will obtain as much butter from a given quantity of milk as can be got by older process. The makers dec'are that the percentage of butter fat lefc in tlso separated milk is very small ; but this* needs vertincation by practice.
