Operating instruction for labor 8. Selection of personnel 9. Preconstruction costing 10. Production costs per unit of material Notebooks must be kept with a daily log of all observations and data. Each page should have a title and date, and at the end of each period a brief résumé must be written of the day's work, signed by initials of the worker and someone who was with him in the laboratory. Notebooks should be deposited with the instructors.Weekly reports to the class are essential, and weekly written reports should be made. The student should receive practice in presentation. Calculations and reasons for making certain decisions should be presented concisely to the class for criticism. The discussions should be informal.At the end of the year a complete report should be turned in which includes all calculations, flow sheets, material balances, plans, and layouts, and a carefully executed drawing on plans and elevation of the completed plant, with such detailed drawings as may be necessary to clarify the drawing.Thus the unit operations and unit processes are correlated not only with each other but also with economic and design considerations of unit process. This is the old industrial chemistry laboratory dressed up to conform to present-day demand.IS THIS the type of course work that will fulfill the need of the students and of the industrialists? And will the industrialist want a man so trained and start him in his plant with only the necessity of teaching him the details ofjhis own process? Literature Cited(1) Chem. & Met.
