Manchester Guardian: “With great skill the knowledge gained from simple experiments in the classroom or laboratory is made effective.... Our old friend the cactus ... and other exotic wonders are happily relegated to very subordinate parts in these bright and attractive pages.” Athenæum: “The author has attained simplicity of language—a more difficult business than writers of textbooks imagine—and as the book is printed in large, clear type, we can strongly recommend it to teachers in schools”. Inquirer: “Is a delightful book, beautifully illustrated”. Scotsman: “The book is a charming guide for the youthful botanist or naturalist to the life history of plants, and it is written with a due regard to the age of those for whom it is intended”. Knowledge: “An excellent book for young people desirous of learning the why and wherefore of plant life”. New Age: “We have seen nothing produced on this side of the Atlantic so good of its kind”. New Phytologist: “... may be unhesitatingly pronounced a great success ... written with a breadth and knowledge he has not met before in an English elementary work”.
