The eggs are pure white, of un-iform shape and average 15-16x11-16. Being badly in need of skins of that species, I collected most ofof the old birds; among them was one female that the red throat-mark very plainly (I never obse]ved any trace of it before.) Hermate was the most beautiful specimen I ever saw, and that samepair occvipied the high tree. Perhaps vanity led them to selectsuch an exalted position. None of those I took were less than 15 feet high, but I oncefound a nest of young only a few feet from the ground, so thathigh nesting is not entirely a rule with THE O. & O. SEMI-ANNUAL. 17 THE GOLDEN EAGLE. - Aqtiila Chrysaetos. BY GEO. F. BREIflNGKR, PORT COLLINS, COLORADO. Confining myself in the writing of this article exclusively tothe distribution and nesting of the Golden Eagle {Aguila chry-saetos) and such notes that may seem proper in the article in con-nection with the bird, I shall endeavor to place before the readeras complete a history of this noble bird as is in my power. Larimer County contains 4000 square miles. The north-easternportion is made up entirely of barren plains, with irregular out-croppings of sand stone that form vv^hat is known as ChalkBluffs, Twin Buttes, while sinaller ones have no particularname at all. Here and there dry creeks are encountered thatcarry water only in times of heavy i^ainfall. At other seasonsthey are perfectly dry. The south-eastern portion is the feilileCache la poudre valley, covered with faims, pastures, etc. Thegreatest part is mountainous
