The article reviews two books: "Vegetable Crops" and "Grain Crops." "Vegetable Crops" is well-illustrated and has an excellent index, but the botanical information is not always accurate. It is valuable for practical use by commercial growers and gardeners. "Grain Crops" is an expansion of lectures given at the University of Minnesota, covering the fundamentals of botany, plant classification, and the culture of grain crops. However, it is heavily biased towards American conditions and lacks references to international literature, making it less useful for students and farmers outside the United States. The article reviews "Crystal Structures of Inorganic Compounds" by Ralph W. G. Wyckoff. The book is a continuation of Dr. Wyckoff's earlier work, providing detailed discussions of crystal structures and their relationships. The content is well-written but includes some awkward phrasing and a lack of commas. The book is published in loose-leaf form, which has its advantages but also introduces some practical issues. The author's use of kX units instead of Angstrom units is a technical difficulty that should be addressed. The book is compared to the "Strukturbericht," and the loose-leaf format is expected to have advantages in organizing data. Overall, the book is appreciated by X-ray crystallographers for its comprehensive coverage and the author's efforts.The article reviews two books: "Vegetable Crops" and "Grain Crops."
