The Nearctic Psammocharids Of The Genus Aporinellus Banks, Joseph Bequaert

Ba

On one of the collecting trips made this summer with Prof. William M. Wheeler, in the vicinity of Boston, I collected a little Psammocharid which has proved to be an undescribed species of Aporinellus. In comparing this specimen with Mr. Nathan Banks' extensive collection of Psammocharids I have found another undescribed member of the same genus. Descriptions of both forms are given herewith, together with a brief review of the group. I am much indebted to Mr. Nathan Banks, of the Museum of Comparative Zoology, Cambridge, Mass., for the loan of rich material containing many types and for valuable bibliographic …

Dairy Barn And Milk House Arrangement, J. H. Frandsen, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

From an economic point of view, as well as from the standpoint of animal comfort, it is highly desirable that adequate barn or shed facilities be provided for the dairy herd. Some farmers have developed the idea that to keep cows healthy and comfortable and to produce sanitary milk it is absolutely necessary to have expensive barns. As a matter of fact, many of the dairy barns where sanitation is the primary object are quite inexpensive. On the other hand, if the barn is conveniently arranged and made to embody the most accepted sanitary features, it is very essential that …

Marketing Nebraska Potatoes, J. O. Rankin

Nebraska Agricultural Experiment Station: Historical Circulars

Marketing Nebraska potatoes is no less important than raising them. It is often much more difficult, yet the pay for this service is grudgingly given. Failure to secure a good market causes more men to hesitate to enter or stay in the potato business than field risks. The full usefulness of the potato has not been secured until it is on the consumer's table. Every process necessary to get it there is a useful and productive process and the grower is no less productively engaged when working to find a market or to get these perishable wares into it than …

New Species Of Water Mites Of The Genus Arrhenurus, Ruth Marshall

School of Biological Sciences: Faculty Publications

About ninety genera of Hydrachnidae are now recognized, with some eight hundred species. About one-fourth of these species belong to the single genus Arrhenurus. Fifty-five have been described for North America, chiefly from the upper Mississippi valley. This paper adds one new species.

On The Specific Identity Of Heronimus Chelydrae Maccallum And Aorchis Extensus Barker And Parsons, Horace Wesley Stunkard

Harold W. Manter Laboratory of Parasitology: Library Materials

The monostomes are among the least known of North American trematode groups. Records give descriptions of only six species, each the single representative of a genus, and according to the classification of Ward (1918) belonging to four different families. Existing descriptions in most cases are far from complete and data necessary for taxonomic determination are lacking. This deficiency has been pointed out by other workers, both in this country and in Europe, and the classification of the monostomes is not well established. In fact, certain investigators regard them as aberrant forms, sprung from different distome groups, which alike have lost …

Bulletin No. 170 - A Study Of Methods Of Determining Soil Alkali, D. W. Pittman

UAES Bulletins

There is a great lack of uniformity in the methods of testing soils for alkali salts and in the forms of expressing the results in a way that will show the relative toxicity of the salts. This has been pointed out by numerous investigators and has been shown to complicate the determinations so much that the results of different investigators are hardly comparable. It is of further disadvantage in that the toxic limits of an alkali as worked out by one system of analysis are often difficultly applicable to a soil that has been tested by another system. However, it …

Bulletin No. 169 - The Use Of Alkali Water For Irrigation, F. S. Harris, N. I. Butt

UAES Bulletins

Because of the scanty rainfall of arid regions, the soluble materials in the rocks and soil are not leached out as they are where the rainfall is high. As a result, the accumulation of excessive quantities of soluble salts is likely to be a menace to arid soils. Farm practices must be directed toward preventing this condition.

Bulletin No. 168 - Relative Resistance Of Various Crops Ot Alkali, F. S. Harris, D. W. Pittman

UAES Bulletins

Plants show considerable variation in their resistance to soil alkali. Some varieties of native vegetation grow only where the salt content of the soil is high. Most of the cultivated plants, on the other hand, are injured very decidedly by the presence of large quantities of soluble salts. To this rule there are a few exceptions such as the date palm.

In most of the arid parts of the world there are sections where the presence of alkali is the chief limiting factor in crop growth. Millions of acres of land are in the border zone between complete freedom from …

Advertising Farm Products, Geo A. Starring

SDSU Extension Circulars

Advertising is now regarded as essential in placing any commodity on the market. Advertising puts goods where they will be of maximum service. It follows that such a place will pay the highest price. Farmers of South Dakota are intensely interested in this phase of marketing. Individual farmers usually look for a local market where the advertising medium is chiefly local. This is especially true in respect t0 the sale and exchange of livestock and seeds of various kinds in smaller lots. A community of farmers who have considerable produce of a certain standard kind might advertise cooperatively to good …

Purebred Sires Effect Herd Improvement, M. N. Lawritson, J. W. Hendrickson, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

The real worth of a sire for the dairy herd can be established only when production records of the progeny are available for comparison with those of the preceding generation. A study of the following three sires which have been in service in the University of Nebraska dairy herd should be of interest to the Nebraska dairyman wishing to improve his own herd. This experiment indicates that the apparently high cost of a good herd sire is more than outweighed by the increase in the value of the progeny.

Bulletin No. 166 - The Climate Of Utah, Frank L. West, N. E. Edlefsen

UAES Bulletins

Climate is of interest and importance to the scientist in general. It is particularly important to the investigator in the field of agriculture because growing crops are affected quite as much by sunlight, heat, rain, and frost as by the fertility of the soil. In field investigations these factors must be determined and reckoned with.

Bulletin No. 167 - The Irrigation Of Oats, F. S. Harris, D. W. Pittman

UAES Bulletins

It is well known to farmers that the oat plant is more sensitive to the moisture condition of the soil than are many of the other farm crops. For this reason oats find favor as an irrigated crop, since under irrigation the supply of water can be so easily controlled.

In order to secure the best results, it becomes necessary to know as much as possible about the moisture requirements of the various crops that are to be irrigated. This is particularly true of oats on account of their sensitiveness. The farmer should know at which period in the life …

Farm Types In Nebraska, As Determined By Climatic, Soil, And Economic Factors, R. R. Spafford

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This bulletin treats chiefly of Nebraska agricultural areas as determined by climatic, soil, and economic factors. Most of the subject matter centers about the kind of farm crops grown and their yields. Cultural practices applied to crops are only incidentally considered. Most of the data used are from the Thirteenth Census of the United States and cover the crop year 1909. The small amount of data not derived from this source comes largely from field studies in this State and is used merely to support certain methods of treating census data.

On A Species Of Hedruris Occurring Commonly In The Western Newt, Notophthalmus Torosus, Asa C. Chandler

Harold W. Manter Laboratory of Parasitology: Library Materials

It has recently been pointed out by Ward and Magath (1916) that the nematode fauna of North American freshwater fishes is almost unknown. From a survey of the literature this state of affairs appears to be almost if not quite as true of the nematodes of other cold-blooded vertebrates in North America.

While making stomach examinations of the Western Newt or water-dog, Notophthalmus torosus, the writer found a large percent of specimens captured in the vicinity of Corvallis, Oregon, infested by a nematode which was evidently a species of Hedruris. The structure and ecology of this worm are …
