SEED-SOWING MACHINES.

The rows in this machine are marked out by a chain, two 

 of which hang near the handles and drag on the ground, 

 being used alter- 

 nately. The wheel 

 is pushed along the 

 mark made by the 

 chain. 



The principle on 

 which the " Snap " 

 machine is founded, 

 s the securing the 

 flow of seed through the aperture by a jerking motion, 

 which is usually effected by a spring which makes a snap- 

 ping noise when set free. 



One of the machines built on this principle is known as 

 the Danvers Onion Sower. (See engraving.) 



The structure is exceedingly simple ; and as it involves 



but 

 few 



hence is but little 

 liable to get out of order, and 

 when out of order can readily 

 be repaired by any blacksmith 

 it was quite a favorite with onion-raisers : but improved im- 

 plements have to a large degree taken the place of it. 



The Danvers machine opens the furrows, drops the sged, 

 covers it, but does not roll it. Farmers usually attach an 

 old horseshoe to the end of the seed-coverer, which gives 

 sufficient weight to make it answer pretty well the purposes 

 of a roller. 



Matthews's Garden Seed Drill is a fine example of the seed-
