NOTES ON SOME OF THE CONTRIBUTIONS TO THE AGRICULTURAL DEPARTMENT OF THE GREAT INDUS. TRIAL EXHIBITION IN DUBLIN.

[Concluded from out lost.] In the sectional diagram we have given in fij*. 13 it will be sfen that the mill consists in the combination of two pairs of stones working together, the one pair placed nbovo the oilier— the upper pair commencing the process, tho lower finishing it. TJnth pairs are mounted on the same spindle, and impelled by the sumo gearing . There i» a space of about 27 or 30 inches between the upper and lower pair, the greater portion of which is occupied with n vertical dressing-machine ; the brushes N N being fixed to the central spindle I, and enclosed in the wire cylinder M M, The upper stones in both pnirs arc fixed, the lower ones revolving. The upper stones me in two jiaitn, each forming » semicircle 1 . Tluy arc bolttil together, and can be ndjiisted by fixed wedges or inclined pinned, on wbicli they rcit. iSy means of a screw actod upon by a wheel, they can be made to slide up or down the wedges, so as to adjust most accurately the grinding space between the atones. The flour, as it falls from Ilia uppcr'stonrs, is brushed through the wire cylinder Mi and lecoived into a wood eating ; tho bran still remains in the mill, and falls by its own gravity to the lower pair of stones ; they complete the process, and leave nothing unconverted into flour which could add cither to tho weight or the quality of the loaf. So short a time is the corn in passing through the mill that the bran falls in , flakes, many of them nearly the entire sUm of tho wheat; and one great advantage of this speed it, that in place of being overheated, as in the old principle was nearly always the case, tho (lour comes away comparatively cold. In fie. 13, Ais the (eed pipe. As the wheat cannot be delivered to the centre oftl'e upper millstonei, this fcedipipc communicates with a hopper B placed on one side ; in tho interior of this hop' per a flat disc or regulator i« made to revolve quickly; the grain fulling on it by the centrifugal force is distributed evenly, and delivered to tho chamber D t which is placed over tho eye of the stonen.

In a scries of trinh at the well known mills of Messrs Pavitt at Wapping, the following were the results :—" The first experiment in the old mill gate a discharge of 16 Ib. of flour in live minutes, which was equal to 102 Ib. per hour t whilo upon the patent mill there was a discharge of 38J Ib. in five minutes, or 462 lb. per houri The difference therefore on that experiment wos, against the old system, 270 lb. per hour. The second experiment tried was even more favourable as regarded the new system. Two conical mills worked against two on the flat principle for an hour, ascertained exactly, and with the following results :— Conical mill No. 1 produced SJ bushels 2 " 1% " Plat mill 1 " 3 " 2 " 3 So favourable an opinion have the Messrs Pavitt formed of this invention, that they have determined to abandon the old system, and, to use their own term, "go tho whole hog" with tho ncwi Here ia an extract from a letter of theirs on the subject :— " We may say in a few words as millers that, at the examination we have held, Westrup's mill, tried ajrninst our best ordinary mills, has been found to do more than douiii.i; tho work in the same gpaco of time than the ordinary mills, ami at a saving of more than one-half of the cost of the steamnpower fuel, and labour usually employed ; in fact, it would be a saving to abandon the old principle at once and adopt the new. That as to the quality of the flour, it is much stronger, and capable of making tt- much greater quantity of bread —which has been proved by respectable bakers to be from three to four, or even more, 4-lb. loaves per sack, and will keep much longer. Thf bran is perfectly open, broad, and clean, showing Unit the flour has not been reduced in quality by constant grinding, as is the consequence in ordinary grinding We are enabled to state, from (be griiiti wehavo made up, that the ' offul ' is much lighter than by our other stoncß, which are allowed to lie the best, and upon the most modern construction upon the old principle. The stones arc dressed about as often as the ordinary stones ; but a« they do double the work this is equivalent only to half the usur.l dressing. Tho stones will give 40 to 50 quarters of wheat without requiring »ny attention whatever in raising or lowerine: them, and they arc less liable to get out of older than on the old principle.' 1 Thesysicm of milling we have now described is oonsideied by those competent to judge as one of the most important invmtions of tho tiny, and as likely to cxircisc a very marhrd influence in the milling trade; we hnve, therefore, bad less hegit"tion in allotting a few pngesto us description aud illustration. It is now boing largely introduced into France, Belgium, Austria, and Mexico ; and with the view of introducing it to the notice of the trndc in Ireland, a working model has been exhibited in the KxMbition, whirs it bos been an object of much interest.

Lady K. Duncnn was an heiress, nnd Sir W. Duncan was her physician during a severe illness. One day «he told him she had made up her miud to marry, and upon his asking the name of the fortu' nate chosen one, she bade him go homo and opon the Bible, giving him chapter and verse, and he would find it out. He did no, and read what Nathan said unto David, "Thou nrt the man."

Three young men rule one-third of the people of the world.
