Looking at the marve1s of Mars through a telescope is big-scale replica of the wonders which the egg test CT sees as he candles eggs for condition and quality. peep through the egg testing device, plus the ability to diff ferentiate between sound and stale eggs, enables the operator to add marked ly to the price of the fresh quality eggs which he sells.
 The shell of a new-laid egg has a soft "bloom," which is the visible sign of perfect freshness. This bloom is de- stroyed by touch, and in any case dis appears after a few days exposure to the air. After that the appearance of the shell is not a reliable indication or the condition of the contents.
 By holding an egg between the eye and a strong light in such a manner that the rays of light come to the eye through the egg, the condition of the contents can be seen This method of examination Is called "candling" This work is done in a dark room. using a light inclosed in a case having opposite the light hole of proper size and shape before which the egg is held for examination.
 HOMEMADE EGG TESTER
 An ordinary hand lamp. lantern, an ircandesoent bulb, or a flash light may be used. Any box large enough to hold the lamp. set on end, can be used for q case. Besides the hole in the side op- posite the light there should be q hole in the top end; otherwise the heat from 1ha Ight would fire the box. A tester chimney such as is used on a lamp for testing eggs in incubation may be used for cardlng.
 For convenience the light should be placed on a table or shelf. The eggs to be tested should be placed at one side of the light, while on the opposite side +Ia should be provided, Each egg should be examined alone by holding it, large end up. clcse to the light perfectly good, fresh egg shows "full'' and clear be- fore the light; there is almost no air cell at the large end, and the yolk out line is only faintly discernible. A hxed ail cell of one-eighth to three-siXteenthS of an inch in depth indicates fresh eec. as eggs run in general. A larger air cell with q mobile lower line indicates according to size and fluctuatons-a stale egg, or one becoming weak and watery. . the eggs are usually blood clots. Large spots rings and shadows are due to heat and examination and indicate decomposl- ton in the first stages. An egg that Is opaque except for a large fixed air cell contains a chick dead a an advanced stage of decomposition. An opaque egg with large ar cell HdNiiS iiO :, line is in an advanced stage or Ilulu Accommodation. Eggs showing soiled spots or rings can often be utilized by break inc them and separating the bad part.
 PRESERVING EGGS
 During the spring and early summer when eggs are abundant and reasohaple in nrice attention should be given to rreserving them foY winter use. fresh eggs. -,roperly preserTed in Watergiass or ire water, may be kept for to F nnonshs Tn excellent condition and used with good results. Eggs laid during April May and early June have been found to keep better than those laid later Tn the season.
 If satisfactory results are to be ob- +a;nad the eggs should be fresh and clean. and if possible infertile. Eggs that float when placed in the solution are not fresh and therefore cannot be pre-
