A review by Vernon L. Kellogg, published in Science in 1907, of Mary Austin's book 'The Flock' (1906), which records her observations of sheep, shepherds, and sheep dogs in California. Kellogg quotes passages on flock behavior (leaders and followers, panic flight, bedding habits), the loss of native instincts through domestication, poisonous plants and water, and the training of sheep dogs. He argues that a literary nature writer's observations can still be of value to scientists.

A 1908 Stanford University monograph reporting Vernon Kellogg's breeding experiments on inheritance in the mulberry silkworm (Bombyx mori), done with Ruby Green Smith. It covers Mendelian inheritance of larval color patterns and cocoon colors, strain idiosyncrasies, double mating, fluctuating variations such as wing pattern and venation, double cocooning, sports, and fertility. A section on the economic value of the findings for silk culture and an appendix of abstracts of the author's earlier silkworm papers follow. Plates show larvae, moths and cocoons of different races.
