What reading level is Ornithology in Relation to Agriculture And Horticulture book?
To quickly assess the difficulty of the text, read a short excerpt:
Merriman, the eminent American ornithologist, "of the sparrow's multiplication, the surprising swiftness of its extension, and the prodigious size of the area it has overspread, are without parallel in the history of any bird." The facts in support of this statement are over- whelming and need not be recapitulated. Just Digitized by VjOOQIC Appendix, 183 a few words here about the phenomenal fecun- dity of the sparrow. " It is not unusual," adds Mr. Merriman, " for a single pair in the latitude... of New York, or further south, to rear between twenty and thirty young in the course of a year.
Assuming the annual product of a pair to be twenty-four young, of which half are females and half males, and assuming further, for the sake of computation, that all live, together with their offspring, it will be seen that in ten years the progeny of a single pair would be 275,716,983,698. But for practical purposes, if we allow three years as the maximum of a spar- row's life, and allowing twenty as a maximum of annual births for each pair, the fecundity is enormous.
