Publisher's Synopsis
Excerpt from Tungsten, Molybdenum and Vanadium, Vol. 4: Compliments of Fletcher Francisco State Mineralogist
This report has been prepared with the same ideas in mind which prompted the publication of Preliminary Report No. 3, on Manganese and Chrome in November, 1917, namely, to satisfy a demand for immediate information concerning the minerals herein treated while a more detailed report is being prepared, and field investigation is being carried on.
In regard to freight rates on the ores and minerals dealt with in this report, it may be stated that such rates are computed on both the weight and value of the shipment. It is occasionally possible to effect a saving by keeping the value per ton of ore below a certain limit. This would, of course, have to be determined for each individual case, depending upon the origin, destination, rate and grade of ore demanded by the buyer. Freight tariffs for both carload and less than carload lots, may be best obtained by consulting the nearest representative of the company over whose lines the product is to be shipped.
