Consider that a college education costs you several thousand dollars, which you might earn by devoting the same time to some remunerative occupation and this regardless of the pocket from which your expenses come. The expenditure will prove an extravagant waste or a money-and-satisfaction-producing investment according to your intention to get the least or the most out of the opportunities purchased by it. The best value can be obtained from these courses by following the suggestions given below: (1) Read the references for each group of tests before undertaking the work. They are the standards of scientific and professional practice. When the work is finished, read them again. (2) Use this laboratory outline as a guide in fitting standard practice to the conditions and equipment of the laboratory. The instructions may be freely modified. (3) Secure, check and record the items of data in the laboratory with careful accuracy, and with indifference as to how they may affect the final result. (4) Check every step in the laboratory, and every calculation so that you may be prepared to affirm that the facts presented are facts, (5) Present these facts in a report, designed with engineering skill, to convey information with the minimum of mental friction to the reader. (6) Buy and use a slide rule and a typewriter. They have become the engineers indispensable tools. EXPLANATORY NOTE. The subject-matter for these courses will be found in the assigned references. The descriptive paragraphs which follow are intended to be supplementary, and are not in themselves either complete or consecutive.
