Srd, 1917, is to be made as follows: — From a fair sample of at least one pound, there is to bt weifrhed out, after thoroughly mixing the whole, two portions of one ounce each. In each of these portions careful inspection is to be made under a lens of low power, and the unground seeds are to be separated, identified, and counted. The sum of those seeds which fall into the class of noxious weed seeds is to be multiplied by 8 ; and the product is the number of such seeds per pound of the sample. Ottawa, 18 January, 1919.

It ia to be bonie in mind that .legal requirementa for bran and aborts do not measure up to the valuea af the beat qteoimeiA of theae reapeotiTe milliAg products. Many aamplea of bnm a>« fbnnd to contain more Aan 14 per cent of protein. The addition of non-protein m»tten to tnah bran, ao long aaTt doea not briug up the fibre content to more than 10 per cent, may be regarded as adulteration from 000 point of view, inaamudi as bran ia Btw imtid to hare nothing added to it other than bran iteelf, but it might be impoaaible^ upon analytical reeulta, to prove such addition. So long as the buyer obtains 14 per cent of proteids, 8 per cen« of fat and not more than 10 per cent of fibres he geU the actnid feed value of legal bran. It would be possible to mix together two aampl» of bran, one having a higher than average value, the other a lower valuer and aeour« a mixtmv legaDy vendable aa bran, and actually consisting of nothing oth« than bran. Where a manufacturer knows that his r^oduot has a value much above the eatabli^tad Icfal minimum, it wotdd aeem to h drantage to aell such product aa a ngiaterad fead, wiih a goaranftee of value Thi however, a mtitter to be conaiderod hj the producer himaelf.
