Hardwood flooring grading racks with compartment for each length of lumber to the mill. When working at capacity, eighty men are engaged in the yards. The lumber receiving depart- ment is under the same super- vision but is lot:)ked after by the yard foreman only, who directs the location of all lumber re- ceived and the way it js .to be piled. A standard piling ar- rangement is recorded on a map and no change is allowed to be made unless fully discussed with the management. Thi. means a great saving of labor and space, besides being very convenient for new hands to,.be- come familiar with the yards in a short ^vhile. The main mill consists of tWo storeys, 90 feet wide and two hundred feet long. The offices are situated on the street end of the building, on the ground floor and consist of local sales, mailing department, account- ant's and general offices, whole- sales sales, efficiency depart- ment, stores and the man- ager's rooms. The treasurer has his office separate from the mill. On the ground floor of the main building are situated the hardwood flooring, mouldings, and breaker up departmeats. Testing Lumber Going Into the Kiln With a view to establishing a good and reliable grade of hard- wood flooring every precaution is taken to manufacture a uniform- grade of material equal to none as far as finish and dryness is con- cerned. The kilns comprise a battery of four progressive kilns twenty feet by eighty five feet each, with a combined capacity of 320,000 feet. No lumber is allowed to enter the kilns before ascer- taining the degree of humidity contained in the lumber. Tests are made of all material going into the kilns. The first test is made by the scalometer, which determines the percentage of humidity in the material about to be dried. If the humidity is above or below a certain percentage it is directed into a slow drying or fast drying kiln according to the amount of humidity required to be dried out. The importance of properly dried out lumber for manufacturing pur- poses is recognized and to that end twice every day a record of the temperatures in the kilns is taken from the recording, thermometers, the air velocity as recorded by the anemometers, the humidity in each kiln is recorded by the hygrometers, and the outside temperature. When a lot of lumber is due to come out a second test is made. This test is very severe, the lumber tested being subjected to a temperature of 450 deg. F. in an electric oven for that purpose. If the lumber under test shows more than 5.6% of humidity it is not allowed out of the kiln. The manufacturing is followed throughout in the same strict
