Excerpt from Logarithmic and Trigometric Tables: Five-Place and Four-Place I have sought to use symbols and equations only in those cases where I could see gain in spelling out their meaning. The practical teacher may rest assured that in this treatise there are breaks in the continuity of reasoning, r need he fear that there is any lack of training in demonstrative processes. Fitting schools will naturally be solicitous to kw if the class using such a text would be prepared to pass such college entrance examinations as may be tried. Of course it is impossible to predict the questions that may be asked in future; but an actual test has been made of all available college entrance examination papers and only one theorem was discovered that has been omitted from the present work, and that one might be called an original since ne of the three texts recommended by this particular University contained that theorem. Attention is called to the solution of problems. Ordinarily the problem is presumed to be solved, and then a demonstration is given to show that the solution was correct. This does t appear to me to be in the line of discovery. I have in all cases started with a statement of those kwn facts which plainly suggest the first step in the solution, then introduced the next step, giving the construction in connection with each stated fact, so that with the completed construction goes its own demonstration and the student sees the road along which he travelled, and understands from the beginning why he started upon it. - author's te.
