Baked Beans as a Hair Tonic.—We have always understood that, as a diet, pork and beans was “filling” but it remained for a California inventor, Thomas H. Bartlett, to find out a few years ago, that it had the property of “filling” the hair into the head and to cause that already in place to “stick to “ its support. In his patent, No. 920,902, Mr. Bartlett describes his hair tonic as consisting of pork fat, bean oil and other specified ingredients, and describes with great particularity the cooking of a very nice edible dish of baked beans preparatory to completing the tonic. Thus in the description forming part of his patent be says: “I take three cups of common white beans and three pounds of salt pork. The beans are par-boiled, and then boiled with the pork for eight hours, and then covered tight and baked for twelve hours.” With brown bread that would make a pretty good Saturday night tea in Boston. An Umbrella Useful with Big Hats.— An umbrella that should be popular with the ladies wearing large hats is shown in a patent, No. 1,008,456, to Leo C. Bail', of York, Pa.

As soon as milk reaches the lowermost row of holes after a little has accumulated in the cup it is drained off from its upper surface and trickles through into the pail body, gradually filling the latter. Any dirt in the cup cannot get into the pail, being retained in the cup, as it cannot pass readily through the holes. If the dirt happens to be of the kind which readily sinks into the milk, it will drop into the bottom of the cup and there remain. The cover can be disengaged and lifted gradually to different angles, thus draining the milk out of the cup and leaving the dirt therein. This requires but little practice.
