[8] Each setting, clutcb, or the full eompleiuent of eggs, usually called a "set," should at once after finding them be marked, temporarily at least, so that in case several sets of eggs of the same species are taken at the same time, each individual set maybe readily separated from others of the same kind. In marking eggs permanently, I consider the following a good way: Eggs should be marked with a soft pencil in preference to anything else, as these marks can always be washed oft" clean, when it is desirable to do so, wliich can not be done when certain inks are used. A good way is to place the catalogue number of the eggs on one side of the hole, and the set number and number of the eggs contained in the set on oppo- site sides. The date of collecting can, if desired, be placed below, and it is well to mark this on at least one e^g of each set. For example, I desire to mark a set of ten eggs of the Sora Rail, Porzana Carolina (Linn.), taken June 14,1890. The check list published by the American Ornithologists Union, is most generally used at present, and I use its numbers in this case. The Sora Rail stands number 214 on this list, and I mark the eggs of the set as follows:. No. 214 is the A. 0. U. check list uuuiber ol' this species. No. 86 the runninj; uamber of (he let No. 10 indicates the number of eggs iu the set. and the numbers below the hole, which need only be put on a single specimen in each set, indicate the date. The next set would also be 214 if of the same species, but the running or current number in this case would be 87, followed below by the number of eggs the set contained. Aside from this a regular record should be kept for each set of eggs taken. Many collectors use regular blank forms for this purpose, which are carefully tiled away. A good sample of such a blank is about G inches square, print
