Excerpt from Industrial Arithmetic Evidence is abundant that there is a place in the school curriculum for an arithmetic leading up to the mathematics of manual training and the sciences and to the problems in vocational fields. The pupil from the school of to-day finds himself sadly deficient in ability to apply his arithmetical knowledge to the mechanical operations in this vocational age. If he enters any of the trades or industries of today, he finds the same inability to apply or make practical use of his grade arithmetic. This is a very opportune time for an arithmetic such as this book purports to be. We are all giving more attention than ever before to the mechanical application of the power of air, water, heat, light, and electricity.
