HOW TO APPLY THE SULPHUR AND LIME. 



Since it seems proven by the foregoing experiments that the 

 broadcast application of sulphur and lime can not be suecessfullj 

 substituted for the application in drills the question arises, How 

 is the application in drills best accomplished? In our experi- 

 mental work we found the application of the sulphur and lime a 

 difficult problem. In 1897 we proceeded as follows: The rows 

 were first opened by using the seed drill with the coverers lifted 

 and the seed boxes empty. The sulphur and lime (which had 

 been previously thoroughly mixed) were then scattered in the 

 open rows by hand, after which the seed was sown by running 

 the seed drill over the rows. 



In 1898 the rows were first opened by means of a home-made 

 wooden marker, the sulphur and lime applied by hand and the 

 seed then sown by a drill made to follow the open rows. 



The application of the sulphur and lime by hand in this way 

 involved considerable extra labor. Moreover, the sulphur and 

 lime were not brought into as close contact with the seed, as 

 seems ne«cessary for the best results; because when the drill 

 passed over the rows the second time to sow the seed the chemi- 

 cals were mixed with the dirt to a considerable extent. It was 

 plain that both of these difficulties would be obviated by a drill 

 rigged to sow sulphur, lime and seed all at one operation; so we 

 had a seed drill for this purpose constructed by a local mechanic. 



As shown in Plate VII, this machine was constructed on the 

 same lines as the ordinary three-row drill used on the Florida 

 " meadows " except that considerable space was left between the 

 wheels and seed boxes for the attachment of boxes to carry the 

 sulphur and lime. The latter were placed in front of the seed 

 boxes in order that the sulphur and lime might fall in the open 

 row ahead of the seed and also to bring the weight as near to 

 the wheels as possible. 



The apparatus for regulating the quantity of mixture to be 

 applied was the same as that used on the seed boxes for regulat- 

 ing the application of the seed. Each box was provided with tw«
