Bulletin No. 36 - Relative Value Of Corn And Oats For Horses, A. A. Mills

UAES Bulletins

This Bulletin reports the continuation of the study of the best nutritive ratio for horses under moderate work. The experiment was so arranged that a direct comparison could be made between oats and corn as the principal grain ration. The work was planned by Prof. J. W. Sanborn, who was then Director of the Station.

Bulletin No. 35 - Steer Feeding, A. A. Mills

UAES Bulletins

The object of this Bulletin is to give and discuss the results of experiments, herein detailed, in regard to the system, prevalent here, "of keeping cattle on hay and other coarse foods during the winter, then feeding grain for a few weeks in the spring just previous to selling. All over the inter-mountain region very little grain is fed, and what little is used is fed with the idea that an animal which has been kept poorly can be filled up with profit in a very short period, just before selling. The idea was to test these questions, and to …

Bulletin No. 34 - Relative Value Of Wheat, Peas, Corn And Barley In The Production Of Pork, A. A. Mills

UAES Bulletins

This bulletin treats of the use of wheat, peas, corn, and barley when mixed with bran and fed to pigs, the idea being to see if, by using one-half bran, the above grains could not be fed with profit, and also to test the relative value of the mixtures.

Bulletin No. 30 - Narrow Vs. Wide Nutrituve Rations For Horses, J. W. Sanborn

UAES Bulletins

In the third annual report of this Station (1892) the result of feeding wide and narrow nutritive rations to horses was given. This trial was favorable to the narrow nutritive ration. This ration was made up of clover, oats and wheat", while the wide ration was made up of timothy and corn. The trial ran through the summer, when the influence of what has been termed heating food, like corn, might be less effective than in the winter season. Many believe that the more varieties of food given the better the result, as the palatableness of food, it is claimed, …

Bulletin No. 31 - Time To Harvest Lucerne. Mulching., J. W. Sanborn

UAES Bulletins

The opinion has prevailed in scientific as well as in practical circles, that hay cut before or during bloom is more valuable, pound for pound, than when cut at a later period, and it is even maintained that the gross product per acre is more valuable. The old assumption, now somewhat modified, that as plants mature a part of the starch and sugar is converted into fibre, and that the nutrition of the stem is moved into the seed, led to the belief that early-cut hay was both more digestible and more valuable than that cut at a later period. …

Bulletin No. 33 - 1. Grazing Values Of Varieties Of Grass. 2. Drilling Vs. Broadcasting Grass Seed., J. W. Sanborn

UAES Bulletins

In the annual report for 1893, we published the result of experiments in grazing nine varieties of grass and clover, plus the grazing value of a plat of all these varieties mixed. There were some unequal conditions in the trial and it was continued over until the present season.

On May 23, two steers were placed upon each of the ten lots, enclosed by wire fence, to remain there for the period of one month, in artier to observe the length of time the varieties would carry these steers and the growth derived from the varieties. Several reasons prevented the …

Bulletin No. 29 - Irrigation: Amount Of Water To Use. Relative Feeding Values Of Timothy, Lucerne And Wild Hay, J. W. Sanborn

UAES Bulletins

In Bulletin 24 are given results of the first three years of experimentation as to the relation between the amount of water used and crop yield, soil fertility, and the exit, through drains, of the matters held in solution in the water applied. In this report are included the results of the first three years, plus those of the past season. The experiment is regarded of the very highest importance in that it deals with the right amount of water essential to the growth of wheat and grass crops, but more especially as it approximately determines whether the materials of …

Bulletin No. 28 - The Value Of Grass In The Production Of Pork: Exercise Vs. Non-Exercise Pigs

UAES Bulletins

This Bulletin treats of the economical use of grain when fed alone or when fed with green grass, and also of the economy of raising hogs on grass alone. Furthermore, the relation of exercise to the economical use of food is treated of. This Bulletin only reports the continuation of the experiment, as enlarged, carried on during the summer of 1892, and reported in Bulletin No. 22 of this Station.

Bulletin No. 27 - Irrigation; Early, Late And Usual, J. W. Sanborn

UAES Bulletins

Bulletin No. 23 reported the results of the first three years' trials in early and late irrigation. The trial reported in this Bulletin is a continuation of the trials reported in the Bulletin. above mentioned. The purpose of the experiment is to ascertain whether water added to the soil very early is so far stored that it will be available later in the season, and whether late irrigation has an injurious effect on the crop through its influence on development of stem and leaf at the expense of the seed; or, again, whether it is necessary to irrigate crops later …

The Habits Of The Aculeate Hymenoptera. Iii, William H. Ashmead

An

Family V. MELLINIDAE. This family (if we can call it a family) is represented in our fauna by one genus with three species, and as these are exceedingly rare, no observations on any of them have been made. Westwood, however, has observed the European Mellinus arvensis burrowing in sand-banks, and Shuckard states the species preys upon Diptera. Kirby and Spence also say it selects the smaller flies, including the troublesome Stomoxys calcitrans.

The subject of my address is one that has been rarely touched by American entomologists, although offering one of the most attractive and richest fields for research and discovery, as connected with it are many problems of biologic and philosophical importance, which if solved, would throw much light upon many of the moted questions of the day -evolution of species, development of sexes, specialization of organs, transmission of acquired characters, adaptability to environment, etc.

While inspecting during the past summer, the fruit orchard of a friend residing in this neighborhood, my attention was attracted by the peculiar appearance of the leaves of a young plum tree. At the first glance, I thought it might be affected by Aphides, but, on closer examination, I found unmistakable evidence of the work of a leaf-cutting bee, in the circular holes in many of the leaves, and on opening one of the coils of leaves, of which there were four or five, I discovered the curious chambers of the bee, each containing a half grown grub comfortably ensconced, …

The Habits Of The Aculeate Hymenoptera. Iv, William H. Ashmead

The species in the genus Pompilus Fabr., judging from the records, seem to have a diversity of habits. According to Westwood, Pompilus niger Fahr. in England provisions its cells with small Lepidopterous larvae; Pompilus fumipennis Zett. with ants, while Pompilus petiolatus preys upon spiders. Now no doubt this diversity of habits will be found correlated by structural differences, which should be used in separating this extensive genus into subgenera. In our fauna, most of our species in this genus, or at least those whose habits are known, feed upon spiders.

Bulletin No. 26 - Sub-Irrigation Vs. Surface Irrigation And Water For Irrigation, J. W. Sanborn, Samuel Fortier

UAES Bulletins

It has long been held that irrigation water applied beneath the surface is better than surface irrigation, in relation to the amount used, the temperature of the soil, the amount of evaporation, washing of soil and yield of crop, including quality of crop received. Though philosophically there would seem to be little doubt that the propositions are well taken, sub-irrigation as an economical process has been over-pres ed by some as a mean of very greatly curtailing the amount of water used . There are those who have asserted that only one-tenth of the water applied by sub-irrigation would be …

Bulletin No. 25 - Fuits And Forest, Shade Adn Ornamental Trees, E. S. Richman

UAES Bulletins

After three years' trial on the experimental grounds we are ready to acknowledge the conditions unfavorable to the growth of strawberries; the high and dry location of the land, coupled with its sterility, make it unsuitable to the growth of strawberries. The first plants were necessarily, on account of lack of time, planted before the soil was fertilized. Manure was applied freely the second and third seasons, as a top dressing, but the ground, being compacted by frequent irrigation, never has been in the proper condition for strawberries, either as regards fertility or mechanical condition. A new bed has been …
