, both microscope and exten-sion camera, and is difficult of accomplishment.This may be to a degree true, as regards photo-graphing the snow crystals, but not as regards the forms ofwater in general, and of many quite tiny natural objects. Much of our photomicrographic work among the frost andice crystals, the dew, etc., has been accomplished by using anordinary low-power (one-quarter size) photographic lens anda home-made extension camera. It is of the many uses of such a lens and combination whichI wish to emphasize in this article. A low-power lens ofthis kind, well stopped down, in combination with a purchasedor home-made extension camera, serves admirably as a low-power photomicroscope for photographing a vast number oftiny natural objects. It is a comparatively easy task, aspointed out in my last article,* to fit a lens to one end of abox, blackened inside and made light-tight, and ones camera,of whatever size, to the other (open) end of the box, with *Page 110, Annual 1911. 259

But suchan apparatus is equally adapted for photographing tiny insects,flowers, mosses and lichens, hailstones, sections of ice and icecrystals, plants, seeds, tiny mineral crystals, etc., etc. Photographing should be accomplished, when possible, out-doors under the open sky (but, of course, not in direct sun-light), as the objects are thereby well lighted up so that alldetails are brought out. 260 Many objects show best against a dense background, andall such should be arranged before a blackened pail, the latterbeing placed in a hor
