The third book of this very delightful series by T.J.S. Rowland shows how man has risen to great heights in the effort to accomplish big tasks. The weaknesses of man’s natural equipment have been overcome by the use of his brain. Man cannot lift great weights , but he invented the lever. He cannot naturally fly but today he is often in the air.
The book takes the reader into the field of physical and chemical science. the book is fully illustrated with many bold effective drawings which demonstrate the topics with unforgettable vividness.
