Book Description
The formation of roots is in some respects one of the least fundamentally understood of all plant functions. Propagation by cuttings is the aspect that will occur first to most gardeners and horticulturists, and it is certainly the most useful application. But any observant traveller in the tropics can notice that some trees have the habit of forming roots in the air. Climbers like Cissus bear long fine strings of roots hanging down. Pandanus trees tend to have stout aerial roots issuing from the bases of the long branches, while the tangle of roots around the trunk of many of the Ficus species is characteristic. In Ficus bengalensis, in particular, stout cylindrical roots firmly embedded in the ground from a height of 3 to 5 meters give support to the long horizontal branches, enabling them to spread still further. In the big old specimen at Adyar near Madras, the spread of these branches all around the tree, each with a strong root growing out every few meters, makes a shaded area under which meetings of almost 5000 people are sometimes held. The history of how the formation of roots on stem cuttings was found to be under hormonal control is worth repeating here.

Book Description
Like that earlier grouse hunter Aldo Leopold, Mark Parman takes to the woods when the aspens are smoky gold. Here, in an evocative almanac that chronicles the early season of the grouse hunt through its end in the snows of January, Parman follows his dog through the changing trees and foliage, thrills to the sudden flush of beating wings, and holds a bird in hand, thankful for the meal it will provide. Distilling twenty seasons of grouse hunting into these essays, he writes of old dogs and gun lust, cover and clear cutting, climate change, companions male and female, wildlife art, and stumps. A Grouse Hunter's Almanac delves into the mind of a hunter, exploring the Northwoods with an eye for more than just game. "Notable and quotable. Parman stakes out original territory and provides a vivid snapshot of the Northwoods."—John Motoviloff, author of Wisconsin Wildfoods: 100 Recipes for Badger State Bounties "Extremely rich and detailed. Parman puts forth original and genuine experiences."—Richard Yatzeck, author of Hunting the Edges

Book Description
Interest in these plants, in addition to their effectiveness against numerous pests, is also because commercial pyrethrum and rotenone insecticides derived from these plants are also comparatively nontoxic to man and other warm-blooded animals. They may be used with safety in the household, for livestock dips and sprays, and on garden vegetables, fruits and canning crops.

Book Description
In an idealistic utopian community in the early twentieth-century West, a father and daughter engage in a battle of wills: “Transcendent.” —Luis Alberto Urrea, author of The House of Broken Angels Set in a remote stretch of desert near the border of West Texas and Mexico at the turn of the twentieth century, this story follows the pursuits of Owen Scraperton as he struggles to establish Pristina, a utopian community based on mercury mining that aims to resolve the great questions of labor and race. As age, love, and experience cause Owen to modify his original vision, his fiercely idealistic daughter Victoria remains true to Pristina’s founding principles—setting them up for a major conflict that captures the imagination of the entire town. The Mercury Fountain combines realistic modern writing with elements from American and Greco-Roman mythology, taking its cue from Mercury, the most slippery and mischievous of gods, who rules over science, commerce, eloquence, and thievery. “Eliza Factor’s first novel, The Mercury Fountain, explores what happens when a life driven by ideology confronts implacable truths of science and human nature. It also shows how leaders can inflict damage by neglecting the real needs of real people. Though the action takes place between 1900 and 1923, the resonances feel alarmingly contemporary . . . Factor counters convention with a sharp sense of character, evocative subplots and the dangerous allure of mercury itself.” —The New York Times Book Review “Factor develops her characters in entertaining ways while building a novel of social realism.” —Kirkus Reviews
