Book Description
Excerpt from University of California Publications in Agricultural Sciences Soil No. 3. Sandy alluvial loam, from Davis, California. Samples were taken from a wheat field at the University Farm, only to a depth of ten feet. This soil is well supplied with phosphoric acid, potash and lime, but rather poor in humus and nitrogen. The sand is of a coarse nature and becomes rapidly coarser, descending from the first foot down to the twelfth, where it is found as very coarse sand.

Book Description
Excerpt from University of California Publications in Agricultural Sciences, 1917-1919, Vol. 3 A survey of the soil and climatic conditions of California soon revealed the fact that most of our grasses, the seed of which is now procurable on the market, could not establish themselves and produce a strong sod on lands not susceptible of irrigation. Over large areas of the state. There are good soils receiving moisture only in the form of rain on which there is no green pasturage for stock soon after the rains cease. This condition may set in as early in the season as May 1, and may continue during some seasons into November or even December. Therefore a perennial grass that will withstand the winter temperatures as well as the long, dry season in the great central valleys would be of great value to the live-stock industry of California. Recent investigations and experiments lead me to believe that I have found such a grass. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from University of California Publications in Agricultural Sciences, 1913-1929, Vol. 2 Perhaps the most interesting thing about these trees is their resemblance to oak trees. In mass effect they resemble small leaved oaks more than walnuts. This is mostly due to the small size of the leaves and to their color, which is a darker or duller shade of green than that of California black walnut leaves. These features, associated with the fact, noted by Disher, that the parent tree stood close beside a coast live oak tree (quercus agrifolia Nee), are sufficient to account for the View, held by a number of persons, that this new form originated through hybridization between walnut and oak. As the seeds were planted in 1901, these trees are now twelve years old. The two retained by Mr. Disher were left in the nursery, which was set out to commercial varieties of walnut (juglans regia) later on by the owner of the farm. He has allowed the trees to stand unmolested, except for trim ming up low-hanging branches. Now they have attained a height of twenty-five feet and have a spread of branches about twenty feet in diameter. Seen among the broad-leaved English walnuts, these two trees present a distinct appearance with their many slender branchlets and their sparse foliage. In early spring and late autumn or early winter the contrast is even greater, because these trees and other specimens of the new form resemble south ern California black walnuts in the brevity of their dormant period. They leaf out very early in spring and some leaves per sist until February. The English walnuts, however, come into leaf from April to June, according to the variety, and by Nov ember are once more leafless.

Book Description
Excerpt from Miscellaneous Studies in Agriculture and Biology In recent years considerable attention has been paid to the Aphididae in the United States, and in Europe as well, and a large amount of literature is the result. In California, W. T. Clarke was the first to make any systematic studies of these insects and his paper, published in 1903, embodies the results of these studies. He listed forty-three species, ten of which were described as new. Two or three of his new species are known at present, but the remainder are unknown. Unfortunately his collection was destroyed in the earthquake of April, 1906, so now it is practically impossible to determine his new species with any degree of accuracy. Following this, there was a period of six years in which there were no publications concerning the Aphididae of California, except some economic bulletins from the Experiment Station. In 1909, both E. O. Essig and W. M. Davidson published the results of their earlier studies. Since then both have added papers occasionally. During 1912 and shortly before, Harold Morrison made an extensive study of the species in the vicinity of Stanford University. He has kindly placed a report of his studies in the authors hands, with permission to publish the records in this paper. The author has been studying the Californian species continuously since 1914. At present there are about one hundred and eighty species known to occur in California. This number will undoubtedly be greatly increased as further studies are made, since to date only a comparatively small part of the state has been covered by collectors. Very extensive collections have been made in Ventura County and in the vicinity of Pomona College, Los Angeles County, by Essig. The San Francisco Bay region, particularly in the vicinity of the University of California and Stanford University, has been carefully surveyed for aphids, collections having been made by Clarke, Davidson, Essig, Morrison, Ferris, and the author. Davidson, Clarke, and Essig have made a few observations in the Sacramento Valley, particularly in Placer and Sacramento counties.
