"Methods of irrigating grain crops are restricted somewhat because of the fact that such crops cover the entire surface of the plot on which they are grown. Objections to the flooding method, based on loss of water by evaporation, have less weight the irrigation of grain than of other crops, grain fields seldom being irrigated after the seed is planted until the grain is high enough to protect the soil from sun and wind. Grain usually is the first crop grown on irrigated farms. For such farms flooding usually is better than other methods, since the preparation of the land for it is easier than for the other methods. Flooding from field ditches is the usual method of handling water in irrigating grain, but the border basin methods are also adapted to such crops. These methods are described in detail in this bulletin, which also discusses the proper time to irrigate, the quantity of water required, and the cost of growing grain under irrigation."--Page [2]

This 1914 volume responds rising concerns regarding the role of the house-fly in the dissemination of infectious diseases, and its relationship to unhygienic conditions. Given the role played by the house-fly in these circumstances, it was decided that a thorough study of its entomological and medical significance was required.

Excerpt from book: II THE NATURAL ENEMIES OF THE TYPHOID AS with every other living creature, nature makes its own effort to limit the abundance of the fly under consideration, and the extraordinary facility for multiplication which the fly possesses is in turn the result of the instinctive effort of the organism to maintain its status in spite of the numerous enemies which confront it. The natural enemies of the house fly begin with the acme of the vertebrate series (man himself) and end with the lower forms of plant life, and we will begin our consideration of these agencies with the latter forms. Fungous Diseases In the autumn it is a matter of common observation that many flies in houses and on the windows become sluggish and frequently die in such positions. The sluggishness may be accounted for in a measure by the advent of cold weather, and as a matter of fact cold weather frequently drives indoors other species of flies of a more sluggish nature than the house fly. In this way the so-called cluster fly (Pollenia rudis), a rather sluggish species, which will be referred to in another chapter, is frequently found in houses in the autumn. But the principal cause of the sluggishness on the part of the house fly in the autumn is the attack of fungous diseases. Sometimes they are found to be dead without any evidence of the cause of death. Later they are seen to be surrounded by a white fungus growth. There is a group of fungi belonging to the En- tomophthoreae, many of which are parasitic upon insects. There are several genera in this group, but the only one which need be considered at present is the genus Empusa. The fungi of this group have been studied by Dr. Roland Thaxter of Harvard University, and it is from his writings that the following statements have been drawn.

The dangers of house-flies to the health of the community have come into such recent prominence that this book should fill a want. The author has a knowledge of these deadly insects because he has the personal experience of practical experiments combined with the instincts of the naturalist. The result is an account both accurate and interesting which should prove of the greatest value. The discovery of the transmission of disease by mosquitoes required the passage of a decade before its essentials were grasped by the public mind; that of the prevention of small-pox required a century. But the dangers of house-flies is rapidly becoming known in consequence of the popular literature, which is growing, describing the details of the lives of these loathly creatures. In this way only can such knowledge be spread—a knowledge which must become general before flies and the maladies they convey can be generally and satisfactorily dealt with. It is of little use to make great discoveries and then to hide them on the musty bookshelves of learned societies. Instead, they should be adapted to practical purposes applied for the good of suffering humanity; and the best way to do this is to bring out well-written, interesting, and easily read books of this kind, so that all who run may read and their readings endure. This book should assist much to accomplish this end.
