There is an idea prevailing that feeding material that makes bones will in- 

 crease their size. It is a subject well worthy of more attention. 



Prof. Mapes. — When a calf is deficient in bone, that is too weak to 

 stand, feeding bone meal to the cow that suckles the calf will furnish it 

 with the necessary material. This fact is well known to many farmers, 

 and that cows eat old bones with great avidity. We also know that phy- 

 sicians are using a solution of phosphate of lime in their practice, and 

 there is no doubt it may be administered to domestic animals with equally 

 good eftect ; and whether, in the case named, it worked a cure or not, it is 

 well worth trying. Many things much more simple have produced won- 

 derful results. 



Dr. Waterbury adverted to the practice of our President Pell in giving 

 to calves, having weak limbs, phosphate of lime. 



RUST ON WHEAT— A PREVENTIVE. 



Solon Robinson. — I have another letter that describes an easy preven- 

 tive of rust on wheat. James Laurie, of White county, Indiana, writes 

 that rust can be prevented by taking a long cord between two men and 

 sweeping it over the field soon after the fog, which he thinks causes rust, 

 has settled upon it, as the rope agitates the grain and makes the water run 

 to the ground, just as it does by a;gitation of wind, which he has noticed 

 always prevents any bad effect from fogs or what are called scalding show- 

 ers, whenever they are followed by a breeze sufiicient to shake off the 

 water, 



SOWING CORN FOR FODDER. 



Warren Hutchins wishes me to say to the club that he does not sow corn 

 and plow it in, but scatters it in every third furrow, just where the two 

 furrows come together, which only takes half a bushel of seed per acre. 

 If desired to have the rows only ten inches apart, scatter seed in every fur- 

 row, 



CORN OR CLOVER TO PLOW UNDER. 



He says : " I feel much interest in the club discussions, and I should like 

 to know why a corn crop is not cheaper and better than clover for manure, 

 as it comes to maturity the first year. Please tell us the best method of 

 managing clover that is plowed under, so as to have the seed come up and 

 stock the land again. I plowed under a piece of clover a year ago last 

 fall ; the next spring I plowed the ground, and sowed to rye, expecting a 

 fine clover stock, but was disappointed. This spring I have planted the 

 field to corn, and the clover has come up very thick and fine." 



LEATHER SCRAPS FOR MANURE. 



Two years ago I obtained a wagon load of scraps of leather, put it in a 

 hole in the ground, and applied lime and ashes to the heap. I have taken 

 ■out some this spring, and put in some corn-hills ; it was about half of it
