" One of Ours," in his letter of 23rd instant, asks what reason I can havo for no accepting his challengo, and says there can be only ono reason. I could .give more good reasons against it, than he could give reasons of any description in its favor. T will, however, content my •self with two or three. First, then*—His proposal would not attain tho desired •end ; and, secondly, supposing T. accepted it, thero would be the great difficulty of obtaining unprejudiced men*-!- cannot call them'judges—to; decide - npon -the merits of a■■ breed of sheep, with which thoy are unacquainted. 1 propose tp. show shoep under two-tooth, so tha,fc there may be no doubt about, their'iiges. Every practical man knows .tiiat sheep, as a'rulej got their two first permanenttceth .t$ from

12 to 10 months old, and that two-tooth sheep could bo shown of any age from 12 to 24 months, and in the same way with the other ages; so, thirdly, it-is: neces sary to provido against this sort of thing, and to ensure that tlie sheep ex hibited shall be as nearly as possible of the-samo age,/ Fourthly—lt is true that Campbell and. Low have half-bred ysheep rf'tl.e ages "Oho of Ours" desires to show; but their sheep have been run ning during a winter of unparalleled severity on -very high country, and are sure to havo lost condition (a general coniplamt in the interior), so that it "would bo doing these sheep an injustice to exhibit them. So much for my reasons for.not accepting hia challenge. The sheep I propose to exhibit are being htmbed this month in the Manuhcrikia, arid ao confident am I that they will bear out all that has been said about their superiority in value of fleece and carcase, that I have no hesitation in offering to bear tlio expense of the erection of a washing apparatus snflieient to answer thc purpose required, if it will but ensure the acccplaiico of my. proposal by tlie principal breeders of the Province. After 7 this, "One of Ours" and his friends can surely havo no objections to bring their precious half-breeds alongside the des pised, though, in my opinion, greatly •superior stock of tho French-Merino.
