Cement Manufacture In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

It is the purpose of this paper to briefly review the history of cement manufacture in the State, to call attention to certain promising exposures of cement rock, and to report upon the first modern cement mill in Nebraska. Not that this State has been slow in recognizing cement as one of the most important modern constructional materials; or slow to recognize the need of developing its natural resources; but due rather to a combination of circumstances. For at least twenty years, many Nebraskans have had in mind the importance of establishing cement plants in this State. Furthermore encouraging inducements …

Shorter Articles And Discussion Simplified Mendelian Formulae, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

I was somewhat surprised by 'Morgan's and Castle's suggestions for a simplification of Mendelian formulae. My surprise was not occasioned so much by the forms these suggestions took as by the fact that any pronounced changes were deemed necessary. I had not only employed the usual formula in my own work but had found no difficulty worth mentioning in understanding the formula used by most other workers in Mendelian fields. My experience with students in elementary courses in genetics had not prepared me for the idea that such formula were particularly difficult. Nevertheless I believe in simplifying the formulae if …

The Possible Origin Of Mutations In Somatic Cells, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

That mutations are accompanied by some change in the germ-plasm is, I take it, indisputable. Have we, however, any reason to suppose that the change takes place within the germ cells? I am not sure, as a matter of fact, that genetists in general regard the gametes as the place of origin of mutations. It is true, however, that experiments in the artificial production of mutations in plants have been limited largely to treatments of the ovaries from about the time of the reduction division to about the time of fertilization. This suggests a belief on the part of investigators …

Shorter Articles And Reports: The Simultaneous Modification Of Distinct Mendelian Factors, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

In another paper on the inheritance of a recurring somatic variation in variegated ears of maize, it was shown that the amount of red color developed in the pericarp of variegated seeds bears a definite relation to the development of color in the progeny of such seeds. The relation is such that the more color there is in the pericarp of the seeds planted the more likely are they to produce plants with wholly self-red ears and correspondingly the less likely to produce plants with variegated ears. Self-red ears thus produced behave just as if they were hybrids between self-red …

Two Lincoln (Nebraska) Typhoid Fever Epidemics Of 1911 And 1912., Herbert H. Waite

School of Biological Sciences: Faculty Publications

On August 29, 1912, I was requested by the Board of Health of the city of Lincoln to make an investigation to determine if possible the origin and cause of an outbreak of a disease reported as typhoid fever which was then prevailing. This outbreak was said to be most prevalent in one particular portion of the city and consequently attention was turned to that portion. Of the cases reported an investigation was made of over 60 individuals and after considering all the probable causes for the majority of those affected the conclusion was reached that all could be logically …

Connecticut Soldiers In The Pequot War Of 1637 (1913), James Shepard

Electronic Texts in American Studies

“With Proof of Service, a Brief Record for Identification, and References to Various Publications in Which Further Data May Be Found.”

The plan of the compiler is to present, for the first time, a complete list of the Connecticut men in the Pequot War, as given in various compilations of the several authors who have made a special study of the subject in connection with the history of one or more of the three river towns; together with the places from which they are said to have enlisted and the authority for the same. We have not attempted to verify …

Some Of The Next Steps In Botanical Science, Charles E. Bessey

School of Biological Sciences: Faculty Publications

When one who has worked long in any

field of science speaks before an audience

such as this he is expected to say something

about the condition of his branch of science

when he began work with meager and

poorly adapted apparatus, to contrast it

with its greatly improved condition to-day,

and to dwell with pride upon the finely

equipped laboratories with costly apparatus

especially designed for particular

experiments, to be found by the twentieth

century scientific student. And 1 must

confess that the temptation to do so was

one difficult to resist, for we who have

grown old in …

Notice Of Newly Discovered Eurypterids In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

A BED of Eurypterids has just been discovered by the Nebraska Geological Survey in the Carboniferous shales of southeastern Nebraska, and thus a new locality is added to the list for the United States. Such localities are somewhat rare, and notice of any and every new one must be acceptable.

The Carboniferous outcrops are confined to some eight or ten counties in the extreme southeastern corner of the state, and though covered heavily by glacial clays, bold exposures occur in proximity to the bolder streams, especially the Missouri River. About a mile south of Peru, on the Missouri River front, …

Some American Lebertia, Ruth Marshall

School of Biological Sciences: Faculty Publications

The genus Lebertia of the water-mites is easily recognized by the character of the epimera. It belongs to a small group of genera, the subfamily Lebertiinae, characterized by the union of the four pairs of epimera into a single group, with their more or less complete fusion. This forms a shield which covers a large part of the ventral surface of the body.

Spraying Apple Trees

University of Nebraska Historical Extension: Bulletin

The degree of success in spraying depends almost wholly upon when the materials are put on and how they are applied. 'The two principal pests that concern Nebraska apple growers are the apple scab and the codling moth worm. There are other injurious insects and fungous diseases common to the orchard, but if the orchard is properly treated for those two the others will in a large measure be controlled.

The Unexpected Occurrence Of Aleurone Colors In F2 Of A Cross Between Non-Colored Varieties Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Before the Mendelian methods of analysis became available, considerable wonder would doubtless have been excited by the "mysterious" appearance in F₂ of one colored grain-purple or red-to every five or six white ones in case of a maize cross, both parents and F, of which had only white grains. An occurrence of this sort has recently been noted in one of my maize cultures and the F2 numbers are explained here as a trihybrid or tetrahybrid ratio. The crosses in question were made primarily for a study of size inheritance and fairly large numbers have been grown. The varieties …
