Results of crossing cucurbits

The writer has on several occasions expressed his views on the subject, crossing of cucurbits. The views expressed have met with some opposition among professional gardeners, horticulturists and many farmers who cling tenaciously to the old notion, that pumpkins and melons will “mix.” So far as I know the results of our work at the station are in harmony with those made by other investigators in both Europe and America. In a former bulletin of this station the results of our work for 1892 were given. In this bulletin will also be found references to some of the literature on the subject

Notes on the Bacteriological Analysis of Water

The recent epidemic of typhoid fever at the college is of interest to us and especially the methods now in vogue with reference to the examination of water for various organisms. During the recent epidemic and previously the well waters in the vicinity of Ames as well as the college water supply were examined at various times. An examination has also been made of water coming from wells of the parties who have furnished milk to the college. It should be stated here that this report is not completed owing to the fact that some of the species have not been sufficiently determined. From the nature of the case it requires a great deal of patient and careful work to run out the different species, so that the biological examination was not completed

The Barberry in Iowa and Adjacent States

Of the 160 species of barberry generally recognized only the following have been commonly cultivated in Iowa; the common or European barberry (Berberis vulgaris), the Japanese barberry (B. Thunbergii), the B. canadensis, B. amurensis, B. Sinensis, B. ilicifolia, B. Fischeri and B. maerocarpa. The B. Fischeri and B. maerocarpa are regarded as synonyms of B. canadensis. The common European barberry, though commonly credited to Western Europe, is Asiatic according to J. Lind\u27s The Barberry Bush and its Law, being a translation from Berberisbusken og Berberisloven

The Flora of Star Island and Vicinity

It was my privilege during the latter part of July and early August to spend a week with the forestry students of Iowa State College on Star Island to give a few lectures on the flora of the region. I desire to express my appreciation of the kindness shown me by the forestry students while in camp and for some specimens. Nearly all of the students contributed in one way or another plants of some kind. I am under great obligations to Profs. MacDonald and Morbeck as well as to Mr. Marshall, the forest supervisor and to Miss Rasmussen for many additional favors; to Mr. C. R. Ball for the identification of the willows; to Mr. R. I. Cratty for the identification of species of the genus Carex, and to Dr. Robinson for the determination of the oaks. In addition to the above collectors most of the plants were collected by P. S. McNutt, my son, Harold, and myself. Professor MacDonald furnished me with the photographs. Mr. Bode and Mr. Geisler made a map of the Island showing the main characteristics of the flora. The list of plants is by no means complete. We made a hasty survey of the region of Star Island, Cedar Island1 and in the vicinity of Cass Lake. The early vernal plants had all disappeared

The Teaching of Plant Pathology

I am sorry that Doctor Melhus because of sickness is unable to be with you to present the subject of plant pathology from the standpoint of a special teacher. I have not had time to get a paper ready for you and what I shall say will be entirely informal and not necessarily a connected discourse. In recent years I have given little attention to the subject of plant pathology at Ames, feeling it is in good hands. During my early career at Ames I had some experience in giving some training to students in this subject

The Address of the President - A Century of Botany in Iowa

A Century of Botany-It is certainly a pleasure to greet you here on this occasion, especially so, because of the nature of the honorable work performed by the scientists of the State of Iowa. It is customary for the retiring president to deliver an address of some kind. In looking over topics which have been chosen by various retiring presidents I find such titles as Local Problems in Science, What We Have Been Doing, The Academy and the People, Science of One Hundred Years Ago, Some Problems of Heredity and Evolution, Two Centuries of North American Lichenology, Botany in Its Relation to Good Citizenship, The Mission and Spirit of the Good Scientist, Conservation, The Cosmology of the Universe. These titles cover a wide range of subjects, and it seems to me that I might discuss for a little while with you A Century of Botany in Iowa

Theodore Roosevelt, the Conservationist

Some years ago, during the administration of President Roosevelt, I had the pleasure of a short stay in Washington. I was the guest of James Wilson, who was then Secretary of Agriculture

A Comparative Study of the Weeds of Central Iowa, Northern Minnesota and Wisconsin

During a short trip made by the writer in northern Minnesota from Cass Lake to Duluth in Minnesota, St. Croix, Wisconsin, and Taylors Falls, Minnesota, some observations were· made on the introduced plants. The route covered was over the Northern Pacific from Minneapolis to Walker and Cass Lake; from Cass Lake over the Great Northern Railway to Duluth, and via the Northern Pacific to St. Croix Falls, Wisconsin

A Day near Muskogee, Oklahoma

In 1921 the writer spent a short time in a study of some of the interesting plants found near Muskogee, Oklahoma. It may be observed here that there have been some very remarkable changes in the region. The writer\u27s first acquaintance with the place was in 1888 when it was only one of the numerous small villages on the line of the Missouri, Kansas & Texas R. R. In 1870 it was the chief town of the Creek nation and now is the administrative center of the five civilized tribes of Indians, with a population of over 50,000. The town itself is situated near the confluence of the Verdigris, Neosho and Arkansas rivers. The rivers have deeply carved into the rolling prairie and the flood plains of the smaller streams are rather narrow, although the flood plain of the Arkansas widens out considerably
