The article discusses the importance of establishing a large dye manufacturing concern to reduce dependence on German products, emphasizing the patriotic and nationalistic aspects of the endeavor. It highlights the potential benefits, including a more scientific approach to industry management, increased cooperation, and protection for inorganic chemical industries. The author, Walter M. Gardner, stresses that the success of this scheme requires a scientific rather than purely commercial management approach. The second part of the article reviews Dr. Oliver Heaviside's third volume of "Electromagnetic Theory," which covers the generation and propagation of electromagnetic waves. The review praises Heaviside's powerful grasp of Maxwell's theory, his intuitive understanding of electromagnetic fields, and his bold approach to mathematical concepts. The book includes discussions on various topics, such as waves from moving sources and waves in ether, and emphasizes the importance of Newton's Third Law of Motion and the existence of the aether. The final section reviews Dr. Henry H. Dixon's book on the ascent of sap in plants, which is part of Macmillan’s Science Monographs. The review highlights Dixon's contributions to the field, noting his patient and efficient work on the problem of water ascent in plants. The review suggests improvements in the book's referencing and the relative focus on different aspects of transpiration versus sap ascent.The article discusses the importance of establishing a large dye manufacturing concern to reduce dependence on German products, emphasizing the patriotic and nationalistic aspects of the endeavor.
