Excerpt: ...The sacked cement is piled usually nine high in a freight car, the minimum car is eight high or l32 barrels and the maximum car is eleven high or 300 barrels. Due to the perishability of Portland cement, it has to be shipped in closed cars to protect it from moisture. This presents a difficult problem in times when a sufficient supply of closed freight cars cannot be had. Under these circumstances, which just took place during the World War, other means of transportation had to be obtained. In this instance the motor truck was used and a great deal of cement was hauled in this manner especially from those plants situated close to large cities; e.i. the Universal Plant situated on the outskirts of Chicago where thousands of barrels of cement were moved daily; and where motor trucks were not available, horses and wagons were used. Under normal conditions the motor truck will probably prove not to be economical for hauling cement over long distances because there will be an increase in the supply of freight cars and a decrease in the freight rate. Valuation of Raw Material Deposits. It is a fact that there are many large deposits of cement materials in excellent condition in most parts of the United States but a false idea is held as to their actual value. The value of many of these ( when I say value I mean commercial value) undeveloped deposits of such materials is necessarily slight. In most of the Eastern, Southern, and Middle Western States there is little or no difficulty in securing lands containing suitable raw materials for cement at prices ranging anywhere from $5.00 to $50.00 an acre, and only exceptional circumstances would permit the paying of the latter sum.
