Scientific American Supplement, No. 275, April 9, 1881. Various

process milling, prepared by Albert Hoppin, Esq., editor of the above-named journal, for the use of one of the statistical divisions of the United States census, which is so at variance, in at least one important particular, with the facts set forth in the paper read by me before the British and Irish millers, at their meeting in May last, that I think I ought to take notice of its statements, more especially as the North-Western Miller has quite a circulation on this side of the water.

      As stated in the paper read by me above-mentioned, I was engaged in February, 1871, by Mr. Christian, who was then operating the "big," or Washburn Mill at Minneapolis, to take charge of the stones in that mill. At this time Mr. Christian was very much interested in the improvement of the quality of his flour, which in common with the flour of Minneapolis mills, without exception, was very poor indeed. For some time previous to this I had insisted to him most strenuously that the beginning of any improvement must be found in smooth, true, and well balanced stones, and it was because he was at last convinced that my ideas were at least worthy of a practical test I was placed in charge of his mill. Nearly two months were consumed in truing and smoothing the stone, as all millers in the mill had struck at once when they became acquainted with the character of the changes I proposed to make.

      I remained with Mr. Christian until the latter part of 1871, in all about eight months. During this time the flour from the Washburn Mill attained a celebrity that made it known and sought after all over the United States. It commanded attention as an event of the very greatest importance, from the fact that it was justly felt that if a mill grinding spring wheat exclusively was capable of producing a flour infinitely superior in every way to the best that could be made from the finest varieties of winter wheats, the new North Western territory, with its peculiar adaptation to the growing of spring grain, and its boundless capacity for production, must at once become one of the most important sections of the country.

      Mr. Christian's appreciation of the improvements I had made in his mill was attested by doubly-locked and guarded entrances, and by the stringent regulations which were adopted to prevent any of his employes carrying information with regard to the process to his competitors.

      All this time other Minneapolis mills were doing such work and only such as they had done previously. Ought not the writer of an article on the origin of new process milling–which article is intended to become historical, and to have its authenticity indorsed by the government–to have known whether Mr. Christian, in the Washburn Mill, did or did not make a grade of flour which has hardly been excelled since for months before any other Minneapolis mill approached his product in any degree? And should he not be well enough acquainted with the milling of that period–1871-2–to know that such results as were obtained in the Washburn Mill could only be secured by the use of smooth and true stones? Mr. Stephens–whom I shall mention again presently–did not work in the Washburn Mill while I was in charge of it.

      In the fall of 1871 I entered into a contract with Mr. C. A. Pillsbury, owner of the Taylor Mill and senior partner in the firm by whom the Minneapolis Mill was operated, to put both those mills into condition to make the same grade of flour as Mr. Christian was making. The consideration in the contract was 5,000 dols. At the above mills I met to some extent the same obstruction in regard to millers striking as had greeted me at Mr. Christian's mill earlier in the year; but among those who did not strike at the Minneapolis Mill I saw, for the first time, Mr. Stephens–then still in his apprenticeship–whom Mr. Hoppin declares to have been, "so far as I know," the first miller to use smooth stones. If Mr. Hoppin is right in his assertion, perhaps he will explain why, during the eight months I was at the Washburn Mill, Mr. Stephens did not make a corresponding improvement in the product of the Minneapolis Mill. That he did not do this is amply proved by the fact of Mr. Pillsbury giving me 5,000 dols. to introduce improvements into his mills, when, supposing Mr. Hoppin's statement to be correct, he might have had the same alterations carried out under Mr. Stephens' direction at a mere nominal cost. As a matter of fact, the stones in both the Taylor and Minneapolis Mills were as rough as any in the Washburn Mill when I took charge of them.

      Thus it appears (1) that the flour made by the mill in which Stephens was employed was not improved in quality, while that of the Washburn Mill, where he was not employed, became the finest that had ever been made in the United States at that time. That (2) the owner of the mill in which Mr. Stephens was employed, as he was not making good flour, engaged me at a large cost to introduce into his mills the alterations by which only, both Mr. Hoppin and myself agree, could any material improvement in the milling of that period be effected, .viz., smooth, true, and well-balanced stones.–GEO. T. SMITH.

      For breachy animals do not use barbed fences. To see the lacerations that these fences have produced upon the innocent animals should be sufficient testimony against them. Many use pokes and blinders on cattle and goats, but as a rule such things fail. The better way is to separate breachy animals from the lot, as others will imitate their habits sooner or later, and then, if not curable, sell them.

      THE GUENON MILK-MIRROR

      The name of the simple Bordeaux peasant is, and should be, permanently associated with his discovery that the milking qualities of cows were, to a considerable extent, indicated by certain external marks easily observed. We had long known that capacious udders and large milk veins, combined with good digestive capacity and a general preponderance of the alimentary over the locomotive system, were indications that rarely misled in regard to the ability of a cow to give much milk; but to judge of the amount of milk a cow would yield, and the length of time she would hold out in her flow, two or three years before she could be called a cow–this was Guenon's great accomplishment, and the one for which he was awarded a gold medal by the Agricultural Society of his native district. This was the first of many honors with which he was rewarded, and it is much to say that no committee of agriculturists who have ever investigated the merits of the system have ever spoken disparagingly of it. Those who most closely study it, especially following Guenon's original system, which has never been essentially improved upon, are most positive in regard to its truth, enthusiastic in regard to its value.

      The fine, soft hair upon the hinder part of a cow's udder for the most part turns upward. This upward-growing hair extends in most cases all over that part of the udder visible between the hind legs, but is occasionally marked by spots or mere lines, usually slender ovals, in which the hair grows down. This tendency of the hair to grow upward is not confined to the udder proper; but extends out upon the thighs and upward to the tail. The edges of this space over which the hair turns up are usually distinctly marked, and, as a rule, the larger the area of this space, which is called the "mirror" or "escutcheon," the more milk the cow will give, and the longer she will continue in milk.

      ESCUTCHEON OF THE JERSEY BULL-CALF, GRAND MIRROR, 4,904.

      That portion of the escutcheon which covers the udder and extends out on the inside of each thigh, has been designated as the udder or mammary mirror; that which runs upward towards the setting on of the tail, the rising or placental mirror. The mammary mirror is of the greater value, yet the rising mirror is not to be disregarded. It is regarded of especial moment that the mirror, taken as a whole, be symmetrical, and especially that the mammary mirror be so; yet it often occurs that it is far otherwise, its outline being often very fantastical–exhibiting deep bays, so to speak, and islands of downward growing hair. There are also certain "ovals," never very large, yet distinct, which do not detract from the estimated value of an escutcheon; notably those occurring on the lobes of the udder just above the hind teats. These are supposed to be points of value, though for what reason it would be hard to tell, yet they do occur upon some of the very best milch cows, and those whose mirrors correspond most closely to their performances.

      Mr. Guenon's discovery enables breeders to determine which of their calves are most promising, and in purchasing young stock it affords indications which rarely fail as to their comparative milk yield. These indications occasionally prove utterly fallacious, and Mr. Guenon gives rules for determining this class, which he calls "bastards," without waiting for them to fail in their milk. The signs are, however, rarely so distinct that one would be willing to sell a twenty-quart cow, whose yield confirmed the prediction of her mirror at first calving, because
