Publisher's Synopsis
People are thinking, but they can think much more. The housewife is thinking about the chemical changes caused by heat in meats, vegetables, and liquids. The sailor thinks about the gold in sea-water, the soldier thinks of smokeless powder and muffled guns; the puddler meditates on iron squeezers and electric furnaces; the farmer admires Luther Burbank's magical combinations in plant life; the school-girl examines the composition of her pencil and analyses the writing-paper; the teacher studies psychology at first hand; the preacher understands more of the life that now is; the merchant and manufacturer give more attention to the demand.
