Under this heading, as occa8ion arises, the Bulletins issued by this Depart- ment will contain, as an appendix, such comment as may seem necessary or advisali upon matters relating to the work of the Department in connection with the administration of the Adulterfttion Act, the Fertilizers Act, the Feeding Stuffs Act or the Proprietary Medicines Act. It frequently happens that correspondents ask information regarding the above Aits, of such a nature that the matter in question possesses general interest, and comment upon it would prove acceptable and useful to others than the immediate questioner.

LABORATORY OP THK INLAND REVENUE DEPARTMENT OTTAWA, CANADA BULLETIN No. 350 FEED FLOUR J. TJ. Vincent, Esq., Deputy Minister of Inland Revenue. Ottawa, November 2, 1918. Sn«, — I beg to hand you a report upon 170 camples of feeds, purchased under the iiume of Feed Flour. This inspection has been rendered necessury in consequence of certain features of the oyeratibn of the Feeding Stuffs Act of 1909, These features were brought to your notici in my introductory letter published with Bulletin No. 311 (April, 1916). Briefly, tf V. , •* 1-ecapitulated as follows : — > ch bear names of definite and distinctive character, are permitted to be s . registration, because standards can be fixed for such feeds uiider Section S6 u > / Jialteration Act. The recognition of this class of feeds finds justification in the fact that all the smaller mills possess local markets for Bran, Shorts and Chop, as defined under our Act, and it is usual for farmers to buy direct from the mills. There is usually little or no accumulation of these feeds at the mill, the whole output being sold as produced. It would be an evident hardship were the miller required to keep distinct his product from each shipment of grain, and to furnish a guarantee of value with the sale. Such procedure would necessitate an increase in price to the consumer, end would not find favour with the farming community in whose interest the Act is framed. Experience gained since 1910 is decidedly favourable to recogrnition of a class of feeds of this kind ; although the temM and standards fixed by Order in Council of May 1, 1911 (published as Circular G. 90S) have been found to be unsatisfactory in several particulars. Objections have been pointed out in Bulletins 254 and 311 — and consequent upon these facts and others brought into notice through extended correepondenoe, it was considered desirable to invite comment by all parties interested, with a view to such amendment as might be found necessary. In August of last year, a Circular (G. 1200) was e^ensively distributed through the kindness of the Canadian Manufacturers' Association, and through our own Food Inspectors. 10478— 1 J Suggestions have been rer cent. From a large number of samples of flour examined by the Bureau of Chemistry, Washington, and reported in Bulletin 13, part 9, the following averages are taken : — Patent Wheat flour (40 samples), crude fibre 0-21 percent. Common Market flour (19 samples), crude fibre 0-28 " Bakers' and family (14 samples), crude fibre 0-22 " Mean 0-24 " In whole wheat flour, ground from the grain inclusive of its husk (bran) the crude fibre may amount to a little over 2 per cent; but all the samples now reported were evidently ground from the grain after removal of the bran; or the bran had been separatcl by bolting after grinding; and it is to a product closely resembling ordinary flour that the term Feed Flour is evidently intended to apply. Of the 125 samples now reported, 63 contain less than 1 per cent fibre; and 30 samples contain less than 0-5 per cent. Fat Content. Between 1 and 2 per cent fat 23 samples. " 2 " 3 " ■47 " « 3 « 4 " 44 " Above 4 per cent 10 ^m Protkin Content. Above 18 per cent protein 6 sample*. Between 17 and 18 per cent protein 6 " " 16 « 17 " "si " IB " 18 « ; 23 " 14 " 15 " 26 " 13 « 14 " 16 " 12 " 13 " 18 « " 11 " 12 " 6 « " 10 « 11 « 3 « Below 10 per cent protein 1 « It is scarcely necessary to add that no vital weed seeds were found in any of these samples. The fineness of grinding precluded the possibility of this. If it be rtsked whether in riew of the data now reported, the Department wouH be justified in recognising Feed Flour as a distinct article from Shorts or Middlings, I must confew to some hesitation in arriving at a decision. If the point be conceded, it would seem reasonable to require Feed Flour to approximate in composition to ordinary flour, in which case the subjoined sUndards would apply : : ^o>«t™e not to exioeed 136 percent. "oteida « legg than 10-0 Fat " " j.o K ^'^'*- • " more than 1-6 " The suggested standards are based on the composition of flours of a low grade such as might naturally be looked for in flour oflfered for sale as a cattle food. With a single exception (No. 5725) all the samples reported would meet such a standard. The alternative mode of treating these feeds would be to require Ihem to be marketed as registered feed, and sold on the basis of guaranteed value. Manv of them so considerably exceed the minimum values suggested as standards for Feed Flours, that it would doubtless be to the advantage of the banufacturer to adopt this method, and sell them as r^stered feeds. Whether or not the convenience to manufacturer and to consumer would out- weigh the loss to the manufacturer incurred by selling as feed flour an article greatly exceeding suggested standard requirements for this article, is matter for the considera- tion of both parties. I beg to recommend publication of this report as Bulletin No. 350. I have the honour to be, Sir, Your obedient servant, A.
