1925 — La vie intellectuelle des noirs de la Caroline du Nord et la part d’influence qu’y apporte la connaissance de la langue et de la littérature française.Résumé
La vie intellectuelle dans toute société dénote le résultat d'une longue suite de progrès accomplis dans les moeurs de ceux qui la composent. Si tel est le fait auquel ont abouti les Noirs de la Caroline du Nord, le but de nos recherches sera de faire comprendre par quel concours de circonstances, de tels hommes ensevelis dans les bas fonds de l'esclavage ont pu naitre à la via intellectuelle. Comment en dépit de tous les désavantages matériels et moraux qui découlent d'une telle condition, un mouvement aussi noble a-t-il pu se produire. [...] Lire la suite

1925 — A study of the fixation of phosphates by soils.Résumé
A study of the fixation of phosphates by soils requires a correct understanding of the terms absorption and adsorption. The term absorption is used in general to designate the process by which a solid or liquid draws into itself, and retains within its structure, or on its surface another liquid solid or gas.

1925 — The elimination of error in taking yields of forage crops.Résumé
A survey of the present-day situation with regard to Field Husbandry experimentation brings out the fact that there is a growing tendency towards developing finer and more accurate methods of procedure in order that experimental error may be reduced to a minimum. Marked progress in many phases of this work can be detected. [...] Lire la suite

1925 — The effect of frost on the germination of corn.Résumé
The value of corn as a cereal crop in the warmer portions of North America has long been recognized, but its dependability in the cooler regions of the continent depends to a large extent upon the variety or strain grovm. In localities where temperature is the limiting factor there exists the ever present danger of frost injury to that which is being matured for seed, and the larger part of Canada, outside of a portion of south-western Ontario, is included in this area.[...] Lire la suite

1925 — INJECTION OF FOREIGN PARTICLES INTO THE BLOOD STREAM.Résumé
The experiments to be described in the following thesis were undertaken at the suggestion of Professor John Tait. He had found (1918) that thigmocytic blood cells i.e. cells which are readily pulled out by capillary attraction on water wetable surfaces, are highly phagocytic. Mammalian blood platelets belong to the category of thigmocytes, and Tait had found that they may ingest small particles of carmine. [...] Lire la suite

1925 — The relation between the chemical constitution of organic liquids and their ability to swell rubber.Résumé
Previous experimenters have nearly all rendered their results valueless for purposes of independent comparison by employing vulcanised or sheet rubber of unspecified, if not unknown, history and composition, such as "black rubber tubing", etc., and in most cases have assumed the swelling to reach a maximum within twenty-four hours. This is an obvious fallacy in the light of the following results. [...] Lire la suite

1925 — The variation in varieties and mixtures of cereal and forage crops with respect to border effect in comparative crop tests.Résumé
During recent years experimentalists have been giving more and more attention to "Methods of experimentation". Far too great a variety of methods have been employed in an endeavour to obtain accurate results for the problem under consideration, perhaps in no other class of experimental work has the complexity of methods in vogue been more conspicuous than in that conducted by the agronomist.[...] Lire la suite

1925 — Studies concerning bean anthracnose.Résumé
Bean anthracnose is of constant seasonal ocurrence in Quebec and the Maritimes and of considerable economic importance. It was therefore thought worth while to study the disease generally. This leads to a consideration of disease-resistant varieties and in view of the importance of physiological specialization as shown by the work of Barrus, Burkholder and Leach it was desirable that work be done to determine what physiological species of C. lindemuthianum, if any, occur in Eastern Canada.

1925 — A study of the influence of electric light used to supplement daylight on oats grown as breeding material in the greenhouse during the winter season.Résumé
In conducting breeding work with oats, some of the material, specially that used for hybridizing and the first generation, is frequently grown in a greenhouse during the winter. Under such conditions a greater ease in handling the material obtains. As a greater control of the environment is possible in the greenhouse than in the field more uniform results can be obtained from the actual process of artificial cross-pollination. Frequently only a few hybrid seeds are produced, and as it is desired to develop as many second generation plants as is possible, it is necessary to have conditions which will favor … Lire la suite

1925 — Methods of experimentation with corn. : Elimination of errors in plot tests.Résumé
The problem of the elimination of error in field experiments is a very comprehensive one. So many factors may operate to influence results that it is extremely difficult to arrive at definite and accurate conclusions. The more fully the investigator is aware of the extent to which his results nay have been influenced by various combinations of factors, the less certain is he that his interpretation of results is correct. Every investigator wishes to obtain accurate data, and to have his conclusions backed by sound experimental evidence. While each investigator realizes that his data obtained from field experiments are not … Lire la suite
