and Laboratory Methods. 1961 



In the one-inch drawers the entire outer edge is beveled to fit the angle of 

 the cleat, and the drawer runs on the projecting edge. In the other drawers a 

 projecting rail is set into the side one inch from the top of the drawer, which 

 serves the same purpose. In this way the drawers fit close to each other and 

 no space is lost. 



The doors of the case may be of glass or paneled with wood. A thin strip 

 of rubber set just inside the jamb, so that the door will press tightly against it 

 when closed, serves as an efficient dust protector. It is a great nuisance, as 

 well as a constant source of expense, to attempt to have a glass cover for each 

 individual drawer. Cases made as above are practically dust proof. 



Each tray should have a neat label giving the serial number, the name and 

 the locality of the specimens it contains. A box, bottom-side up, can be used 

 for separating the genera and species in each drawer. Small labels of con- 

 venient size for use in them can be had, already gummed, at any bookseller's,

The Kitchen of the Twentieth Century. 



This new kitchen to which we are rapidly approaching shall justly be termed 

 the laboratory of the household. It will be equipped with carefully made stoves 

 with applied fuels and thermometers, doing away entirely with guess work ; such 

 a kitchen will not under any circumstances contain either a wood or coal stove. 

 Labor saving contrivances will be kept at hand and constantly used ; a dish 

 washing machine will have its own special table at a convenient and proper 

 height. Cooking tables will be covered with zinc or some form of tile not perish- 

 able, that will entirely remove the necessity of scrubbing. The walls with round 

 corners will be hard, and composed of material easily washed and made anti- 

 septic. The sink will be ceramic, with either slate or marble drain boards, with 

 a large marble slab at the back, and will be entirely free from any form of wood 

 work. All pipes will be in view, so that they can be readily cleaned ; traps 

 made to open easily, and the cook provided with necessary tools for the operation. 

 There will be a small closet in the kitchen, holding chemicals for cleaning spigots, 

 boilers, and the necessary metal utensils. These, however, will be few, as all 

 utensils will be made of materials that require washing only ; scouring and scrub- 

 bing will be things of the past. Stains or grease spots will be neutralized, 

 chemically treated, not scrubbed. 



A microscope will have the most convenient and lightest place in the kitchen, 

 and will be in daily use for the detection of adulterations ; the examination of 

 moulds and other products of infection. By its aid the housewife will learn the 

 different yeasts, moulds, and bacteria, how to select the first and avoid the others. 

 And then, too, by the aid of the microsccope, she will be enabled to save at least a 

 fifth of her daily allowance and provide her family with much more wholesome 

 foods. For instance, when she buys arrowroot, it will be examined at once to 

 see whether she has received arrowroot, for which a high price has been paid, or
