3d. As a general matter it takes 4| bushels of average wheat, or 

 270 pounds to make a barrel of flour weighing 196 pounds. Upon 

 this system nearly all the meal that ordinarily becomes incorporated 

 with the several varieties of offal is saved and put into the barrel, 

 and is added to the yield, which is a saving of from 40 to 52 pounds 

 of wheat over and above the average amount of flour used in every 

 barrel of flour, as now manufactured, 



4th. From 25 to 50 per cent of time is saved in grinding upon 

 this system, over the ordinary mode, and the work done much more 

 evenly and regularly, as the usual difficulty of specking the flour with 

 the bran is entirely obviated, and the contingency of having super 

 flour cut down to fine, with common skill in grinding cannot take 

 place. 



5th, This system will produce the best Hot Climate Flour known 

 in the world. It is an admitted fact that the bran, which upon the 

 common mode of grinding necessarily incorporates itself to some ex- 

 tent with the meal, is the chief cause of the flour souring in hot cli- 

 mates. 



6th. In addition to the unhfaning of the berry, the wheat under- 

 goes an operation which superadds to the hot climate principle, and 

 which must supersede every other plan to preserve sweetness in the 

 flour. This will be found to be ot great importance to the shipping 

 interest, and to the dealers in hot climates, especially. 



Major Hancock also presented a letter from Mr. Sparum, of Penn"* 

 sylvania, on the subject of yellows in peach trees. 



PROPAGATION OF THE VELLOWS IN THK PEACH. ITS PREVENTION. 



For many years the peach tree has been subject to a disease known 

 as the yellows. This disease seldom makes its appearance before 

 the tree has arrived at maturity, as its great vigor and rapid growth 

 appear to preclude the developement of the disease previous to the 

 tree fruiting. Much time, labor and research, have been spent in 

 fruitless endeavors to eradicate this disease after it has made its ap- 

 pearance in orchards, and the only result arrived at is the necessity 

 for replanting new trees, to take the place of old ones at short inter- 

 vals of time. Many applications to trees have been recommended, 

 and potash, lime, tabacco, banking up trees in winter, &c., have 

 had their advocates. Although individual cures may have been 

 effected, or decay for a time arrested by the remedies, yet such instan-
