Birds Lightest in November Careful weighings of the North American house-finch (Carpodacus mexicanus frontalis), carried on throughout the year, show that in November the adults reach the minimum average of weight. J. L. Partin made more than 1,000 weighings of 800 individuals, and although the differences are not large, the lowest average (in November) being 93-7 per cent of the maximum which occurs in February, they point to a definite seasonal rhythm (Condor, 35, 60; 1933). From December to February, during which period the weight of both sexes surges upwards, the male birds were the heavier, but from April to July the weights of the females were consistently greater than those of the males, a difference due to the relatively greater increase of ovaries during the breeding season. Linsdale found a similar preponderance of weight in female fox-sparrows (Passerella iliaca) during that period.

The Wissahickon Hills: Memories of Leisure Hours out of doors in an Old Countryside

I LOOKED up the Wissahickon Hills in my large atlas and did not find them; I discovered Pennsylvania to be an immense State, and that the Alleghany and Blue Mountains tail off in its central parts into a welter of hills and streams. I saw that the author is a professor of English literature, and I thought that this is no book for NATURE. I took the book to bed and I read “The Fox Sparrow” I had never heard of him, but I was charmed with the “big bouncing fellows” with their “high spirits that come from good shelter and full craws, sunlight and the urge of spring”. “In Praise of Wild Cherry” attracted me next, and this was followed by “The Kentucky Warbler”. I am still a yokel at heart, and I dreamt of my own hills and my father's farm-yard. “The Famous Darking Fowl” came next day, and I have never been able to leave this book alone since. The Wissahickon Hills: Memories of Leisure Hours out of doors in an Old Countryside. By Prof. Cornelius Weygandt. Pp. xiv + 366 + 10 plates. (Philadelphia: University of Pennsylvania Press; London: Oxford University Press, 1930.) 17s. net.
