We are soon to have a new method for selecting mothers for seed production. Details of the same are not yet public. It is claimed that it will be possible to grow seed that will yield beets of a given quality determined in advance, a problem which has hitherto been thought impossible. It will surprise many of our readers to learn that if "tops" or even half beets are planted, they will give seed, the quality of which is about same; showing that as soon as seed stalks commence to appear, the _role_ of the root proper is of secondary consideration, as it serves simply as a medium between the beet and soil(?) Sprayed water may be used with considerable success in washing sugar in centrifugals; it is claimed that this new process offers many advantages over either steam, water, or use of _cleare_. White sugar to be washed is thoroughly mixed with a sugar sirup supersaturated. The whole is run into centrifugals. The sirup swung from the same is used in next and following operations; when it becomes too thick it is sent to the vacuum pan to be regrained. The operation of washing lasts less than two minutes; three quarts of water are necessary for 200 lb. sugar. The water spray at a pressure of 5 to 10 atmospheres is produced by a very simple appliance. Total weight of refuse cossettes obtained during last campaign was 4,000,000 tons, about 700,000 tons of which were sold for $1,000,000; if what remains is dried, it would be worth $5,000,000. Several sodic-baryta methods have been recently invented. Of these we will mention one where 1/4000 to 1/2000 part of calcined soda is added |
