The "Secretary"--Single. 



For a quarter of a century the revolving disk has been known as the best means 

 of cutting and turning the soil, but the difficulty of keeping it at a uniform depth in 

 the ground and in a straight line of progression, setting as it does an angle to the fur- 

 row, has prevented any general success of it as a plow for opening up and turning the 

 furrow. We have been experimenting in this line some years, and have at last hit upon a 

 hooked-shape tine which penetrates the soil, pulling the disk any desired depth and 

 holding it to a straight furrow line. In this we claim an invention of rare merit, and 

 its operation has only to be seen to commend it. 



This new implement, which we now place on the market, is the outcome of a de- 

 mand emphasized by the Secretary of Agriculture, who asks that a plow shall be in- 

 vented that shall not leave the earth over which it passes so impact by pressure as do 

 the plows now in use. 



In shallow tillage, with a cut say four inches in depth, the leverage of the plow 

 point against the earth, the whole weight or power of the team producing a downward 

 pressure at the cutting edge of share, leaves the base of the furrow that is turned over 

 smooth and hard. In fact, it renders it almost impervious to water. Therefore, when 

 a torrential rainfall comes upon land thus plowed and lying upon a land slope, the 

 wash is enormous, and all the good surface earth is carried away. Furthermore, the 

 water being unable to percolate through the subsoil, drains off and leaves the subsoil 

 dry and hard. 



By the use of the "Secretary" the ground is left in an entirely different condition. The disk 

 scoops out the furrow, and in throwing it over thoroughly pulverizes it. The bottom of the furrow is 

 left by the disk in its thoroughly natural condition: that is: there has been no dow i ward pressure on or 

 sliding over of the surface to make it hard and smooth. The penetrating point, which runs under the 

 disk, thoroughly breaks and stirs up the subsoil, and leaves it in the best passible cmdition to receive 

 and retain moisture. The result is that in very heavy rains, the water, instead of running off, will 

 sink down into the subsoil, and when dry weather comes on will be drawn up to supp'y moisture to the 

 plants.
