88 from the nest, this being necessary in order to secure an image of the desired size with the short focus lens at hand (a B. and L. Zeiss Anastigmat, Series II A, 6$1/2$ x 4$1/4$ focal length 5$3/8$ inches). Fifty feet of rubber tubing, a large bulb, and a field-glass made it possible to watch developments and carry on operations from a safe distance. But, although the camera was nearly concealed with ferns and leaves, this day&rsquo;s proceedings were not rewarded with much success. The birds proved exasperatingly timid, and returned only after prolonged waits, to disappear instanter on the click of the shutter (a B. and L. iris diaphragm shutter). So we left the field, not disheartened but bent upon improving our paraphernalia. A day or two later found the camera again in position, but this time with tripod green-painted

and the whole unsightly top enveloped in a green hood with only a small aperture for the lens. This ruse succeeded fairly well, and during the three or four hours that the light was good on this day, and during a like period on a subsequent day, a number of exposures were made that resulted in an interesting series of negatives, giving good prints and still better lantern slides.

Only one of several time-exposures turned out perfect. It is here presented, not only as the prize picture of some three hundred negatives made during the summer of 1898, but as the sole and only entirely satisfactory outcome of some twelve or fourteen hours&rsquo; work.
