 be for any length of time ; if so, there can be a 

 pebble or something else substituted that is con- 

 venient to be placed under the outer stile of the 

 gate.

 CONE'S DYNAMOMETER. 

 Gentlemen, — I send you a rough drawing and 

 description of a very cheap, simple, and effec- 

 tual dynamometer. Every farmer can have one 

 if he chooses ; the only thing is to hit upon 

 some plan to have them uniform throughout the 

 Union. 



Mr. Cone exhibited his plan at the Genesee 

 Cattle Show and Fair, in October. The time 

 was so short, however, after the ploughing 

 match was over, that it could not be applied to 

 any of the ploughs. It was sufficiently tried, 

 however, to satisfy any one as to its accomplish- 

 ing all that could be required of the most per- 

 fect instrument. 



Take the beam of any patent scales that will 

 weigh as high as 10 or 12 cwt. Suspend it by 

 the upper hook, and put sufficient weight upon 

 the lower hook to balance the beam. Then 

 hang upon the small end a one pound weight, 

 and put sufficient weight upon the lower hook 

 to balance. Ascertain the number of pounds 

 upon the lower hook requisite to balance the one 

 pound. The beam used by Mr. Cone required 32 

 lbs. on the weight hook to balance one at the 

 small end. Hitch the lower hook to the clevis of 

 the plough, and the team to the upper hook. The 

 small end runs out upon the land side, at right 

 angles to the plough. From the small end of 

 the beam bring a wire near to the handle of the 

 plough ; attach to this wire the upper end or 

 hook of a common spiral balance, and make the 

 other end of the balance fast to the plough. — 

 The spiral balance becomes the index to the force 

 required to move the plough. Thus if the index 

 of the balance marks fourteen pounds, then the 

 force exerted on Cone's scale would be 14 X 

 32 = 448 pounds. 



You perceive at a glance, that the principle 

 is perfect. It brings the index directly under 

 the eye of the ploughman, and it is easy of ap- 

 plication to any other subject, when it is desira- 

 ble to ascertain the force necessary to move a 

 ponderous body. 



In applying it to a plough, it should be so 

 constructed as to work perpendicularly instead 

 of horizontally. This could be done by having 

 a guide made fast to the beam in which the beam 

 of the dynamometer should play. The balance 

 could then be made fast to the upper slat or round 

 of the plough, and be more convenient for obser- 

 vation ; besides it would not be effected by any 

 inequalities on the surface of the ground. 



Unless some person takes up the subject, I 

 fear we shall not have a uniform scale. I wrote 

 to Mr. Ellsworth, the Commissioner of Patents, 

 asking him to give the dimensions, and then we 

 should have it uniform throughout the Union. 

 If no other person does it, I will prepare one by 

 the first of February. 



Sincerely yours, 



T. C. Peters.

I send you the above as a 

 very useful and convenient table that I have 

 compiled for the " Planter." The calculations 

 are, I believe, entirely correct. 



Permit me to congratulate you on the March 

 number. It is worth all the money I ever paid 

 you. 



Yours respectfully,

 FENCES. 



Messrs. Editors, — As materials for fencing 

 are becoming more scarce every year, in this 

 part of the State, our farmers have been turning 

 their attention for some time to the means of 

 lessening the expenses which are continually 

 occurring, to- keep their farms in suitable repair. 

 Our fences are either the worm, post-and-rail, or 

 thorn. Unfortunately for us, ihe thorn has been 

 attacked by insects, which have injured it ex- 

 ceedingly — in some instances it has been almost 

 destroyed. The post-and-rail fence has now 

 become very expensive, in consequence of the 

 scarcity of white oak timber — the best of which
