Replacing the Horse

Description: I have been working with horses as imagery for about seven years and my problem in lieu of thesis continued along this vein by researching the roles of the horse in history, specifically mobility, and developing work that creates visual links between the past and present roles of horses. I am a printmaker and the work involved in the project consists of prints that use layers of related images and juxtaposition of unrelated images to accomplish my goals of cohesion between horses and the machinery that has replaced them. As the project developed the links between past and present society became my impetus rather the horse and mobility, and my future work will respond to this.

The Use of Windmills in Irrigation in the Semiarid West

Description: "Within the semiarid region there are millions of acres of rich, fertile land, now barren, some of which will be reclaimed through irrigation, but most of which can not be irrigated on account of the limited water supply, and must be farmed, if at all, without irrigation.... This land is now attracting eastern farmers who are prone to risk failure in view of the possibilities in years of favorable precipitation. There have been many deplorable failures during the recent years which could have been averted had the unfortunate settlers fortified themselves against periods of drought by irrigating small parts of their land holdings. It is realized that to accomplish this requires an outlay of capital and if this outlay is great it precludes the possibility of such procedure. With a view to helping these settlers, this Office has investigated the use of windmills as a means of pumping water for the irrigation of small areas in connection with the farming of more extensive areas without irrigation. It is the purpose of this bulletin to set forth in a simple, comprehensive way the possibilities of irrigation, using windmills only as means of power." -- p. 5

Laying Out Fields for Tractor Plowing

Description: Revised edition. "Tractor plowing usually requires methods of laying out the land different from those followed when plowing with horses and an ordinary plow. Farmers plowing with a tractor for the first time are often at a loss for the most satisfactory methods of laying out their fields.... This bulletin embodies the descriptions of methods found best suited to their conditions and recommended by a majority of several hundred tractor owners who have reported their methods and experiences. Among these will be found methods of laying out land suited to nearly every farm in this country and to fields of different shapes." -- p. ii

Laying Out Fields for Tractor Plowing

Description: Revised edition. "Farmers who have been accustomed to laying out their fields for plowing with horses and an ordinary plow are often puzzled as to the best method to adopt when they change to the tractor. For not only are the two methods different, but a lay-out admirably suited to a tractor of one size under certain field conditions may not do for one of some other size under other conditions. This bulletin describes methods and plans for laying out fields for tractor plowing suited both to rectangular fields and to fields of irregular shape." -- p. ii

Laying Out Fields for Tractor Plowing

Description: Revised edition. Report discussing "methods of laying out fields for tractor plowing, of which there are two classes: 1) the method in which fields are laid out so that when the field is plowed the plow bottoms are taken out of the ground at the ends of the field and 2) those methods in which fields are laid out so they can be plowed without lifting the bottoms out of the ground in crossing the ends. The advantages of both methods and their suitability for different farming purposes are discussed." -- p. 1

The Use of Windmills in Irrigation in the Semiarid West

Description: "Irrigation has reclaimed many and will reclaim more of the millions of acres of rich, fertile lands of the semiarid region that now are unproductive. Most of this land, however, cannot be irrigated because of the small supply of water, and farming, if done at all, must be without irrigation. True, the farming has been made less hazardous by the growing of drought-resistant crops and the application of improved methods, but success always is threatened by more or less frequent periods of drought. Many failures could have been averted if the farmers from the East who had settled in these regions had provided against such droughts by irrigating small parts of their holdings. This bulletin is intended to aid the farmers by setting out in a simple and comprehensive way the possibilities of the windmill in irrigating small areas in connection with larger tracts farmed without irrigation." -- p. 2
