Describes methods for collecting, killing, and preserving insects and larvae for displays to be used in the school classroom or by amateur collectors. Also includes instructions for raising live insects in breeding cages.
"This bulletin briefly traces the circumstances which have created the soil problems in the southern Great Plains and shows how the hand of man has hastened present troubles. But it goes further and deals with the methods now being used to solve the problem on nature's own terms." -- p. 2-3. Some of the solutions discussed include contour farming, terraces, water conservation techniques, crop lines, and revegetation.
Describes the damage that can occur to property and people as a result of fire; and discusses various farm construction projects that prevent a fire or offer protection should a fire occur.

Revised edition. "Most wool growers need to know more about wool grading, whether they expect to grade wool or not. This bulletin contains information about the subject so growers interested may improve their position when they are ready to sell their wool. It also suggests ways to handle the wool so that its quality will be maintained through the shearing and the preparation of the fleece." -- p. ii
"Grasshoppers in a single year have destroyed crops valued at over a hundred million dollars. The best way to prevent losses is the use of poisoned bait supplemented by tillage and seeding methods which restrict egg laying and imprison the young grasshoppers in the ground after they hatch. Bait is most effective while grasshoppers are still on their hatching grounds or massed along field margins. It should be put out when grasshoppers are doing their first feeding of the day. This usually occurs between 6 and 10 a.m. at temperatures of 70° to 80°F. Bait should not be spread unless grasshoppers are actively feeding. In mixing and distributing the poisoned bait care should be taken to prevent injury to persons and farm animals. Seeding grain only on plowed or summer-fallowed ground and plowing infested stubble before the eggs hatch greatly reduces the quantity of bait needed for control and decreases the liability of crop injury. Cooperation in the use of control methods by all the farmers in a community is necessary for best results." -- p. i
"The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.
"Revegetating deteriorated range lands by sowing adaptable, nutritious, and palatable grasses is vital for adequate forage production in the Intermountain region, for profitable livestock raising, and as a safeguard against flood and erosion damage. The effect of serious droughts, greatly aggravated by overstocking, has resulted in the replacement of valuable perennial grasses by annual weeds and grasses that have much less value as forage for livestock or for proper soil protection. The abandonment of unsuccessful submarginal croplands has also added greatly to the vast acreage of deteriorated but potentially productive range lands of the region in need of revegetation. Proper guides and procedure for revegetating run-down ranges and abandoned dry farms by artificial reseeding are necessary to safeguard against costly pitfalls and to insure reasonable success. The procedures herein outlined are based on the experiences and research to date and should prove helpful to those administering range lands and producing livestock in the region comprising Utah, Nevada, southern Idaho, and southwestern Wyoming, commonly referred to as the Intermountain region." -- p. i
