White. — Marine Animal Oils 85 



The condition of the market in December, 1913, may 

 be best shown by the following quotation : l "Authorities 

 estimate this season's yield of oil will come fully 40 per 

 cent, short of last year's output. Crude Southern oil was 

 offered at 33 cents per gallon, f. o. b. Baltimore, but 

 there were no buyers at this price. Northern oil was 

 nominal at 36 to 37 cents per gallon, most sellers asking 

 the outside figure. The pressed grades were steady in 

 the face of a quiet demand. There was a moderate in- 

 quiry for the light pressed. Prices closed unchanged as 

 follows : light and brown strained, 40 to 42 cents ; yellow 

 bleached, 42 to 44 cents; white bleached, 44 to 45 cents 

 per gallon." 



Menhaden oil is used in the leather industry for curry- 

 ing, in soap-making, and in the paint and varnish indus- 

 try as a substitute for linseed oil. Its use for rubber 

 substitutes, etc., is kept a trade secret. 



"The oil that gives the best and most lasting results 

 for paint purposes is menhaden oil, and the winter 

 bleached variety is the one that should be recommended. 2 

 This is an oil fairly pale in color, with an iodine number 

 of 150 or over, and with little or no fishy odor. . . . The 

 results I have obtained from the proper grades of fish 

 oil . . . warrant me in saying that fish oil in the hands of 

 an intelligent manufacturer, and used up to 75 per cent., 

 produces excellent results for exterior purposes. For 

 interior purposes fish oil does not seem to be desirable, 

 for it gives off noxious gases for a long time." 



"Menhaden oil should, of course, be used with a drier, 

 and for that purpose the best results are obtained by 

 means of a Tungate drier. Tungate drier is one in which 

 tung oil or China wood oil is boiled with a lead and man- 

 ganese dioxide, and when the solution is complete, this 

 is then mixed with a properly made resinate of lead and 

 manganese. Such a drier becomes soluble in the oil at 

 temperatures over 100° C, and hardens the resulting
