524 WHAT IS THE ' WASHINGTON EAGLE”? 
It is astonishing how equable a climate can be obtained by a 
simple device of this kind. The drawing given on p. 359 
is from such a rock-cave constructed in the grounds of one 
of our most scientific and successful nurserymen near York, 
where he grows not only our royal so-called "flowering fern," 
the Osmunda regalis, and several foreign allied species, but 
the most beautiful of all this beautiful tribe, the moisture- 
loving Killarney fern, which clothes the soil of the damp 
dark woods by the Tore waterfall. 
The beauty of these horticultural experiments is that they 
ean be tried on so small a seale, and are thus within the 
reach of almost every one; yielding a source of pure and 
healthy enjoyment which few other pursuits will afford. Mr. 
Robinson almost promises us that his little book shall be the 
first of a series of similar manuals on different departments 
of gardening ; and we can hardly conceive a greater service 
than this to a large number of his countrymen, who merely 
require to be told how to set to work to cultivate this fasci- 
nating science. — Quarterly Journal of Science.

WHAT IS THE “WASHINGTON EAGLE"? 
BY J. A. ALLEN. 
Editors of the AMERICAN NarURALIST: Sirs :— Will you please inform 
me through the NATURALIST or otherwise, whether you have ever known 
of the Washington Eagle (Haliaétus Washingtonii), being captured or 
seen in New Hampshire. I have an eagle in my possession which I think 
is the ** Washington Eagle." It was caught last spring in Goffstown, near 
Manchester, N. H. It isa large bird, measuriug eight feet from tip to tip 
of wings, three and one-half feet in length, and weighs fourteen and one- 
half pounds. I have also two other eagles, a Golden, and a Bald Eagle. 
The Golden le mea seven and one-half feet from tip to tip, three 
feet in length, and weighs twelve and one-half pounds. The Bald Eagle 
measures seven feet in extent of wings, and three feet from point of beak 
to end of tail, and weighs eleven pounds. Ithink that the Bald Eagle has 
a differently shaped beak from the other, and that is why I am in doubt
