184 APPENDIX. 



. It is, however, the experience of Girardin, Fauchet, 

 and Dubreuil, that large doses (more than 370 Ibs. per acre) 

 increase the straw rather than the grain, and make the crop 

 lodge on soil that has been dunged. 



16th. It is said that the small applications of salt make the 

 straw of the grains brighter, and prevent rust. 



17 'th. It is said that large applications delay the ripening of 

 the grain. 



18th. It is said that salt prevents potato rot (by delaying the 

 sprouting and blossoming of the plant, so that the critical pe 

 riod of its life is brought after the hot fogs and rains of late 

 summer?). 



19th. We know, from many trials, (those of Kuhlmann, and 

 recent ones of Liebig,) that salt often remarkably heightens the 

 effect of other powerful manures. 



20th. We know (from the studies of Way and Eichhorn) 

 that salt is able to displace potash, ammonia, and lime from in 

 soluble combinations of these bodies, combinations such as, 

 in all probability, exist in the soil. Therefore, and because 



2lst. We know that salt increases the power of water to 

 dissolve the phosphates of lime, magnesia, <fcc., 



22d. It is probable that its use may, on certain soils, be 

 equivalent to an application of these bodies, by rendering the 

 stores of them already existing in the soil available to crops. 



23d. It is probable that salt is sometimes advantageous, not 

 so much as a fertilizer, as by destroying worms and the larvae 

 of insects. 



24th. It is certain that fields well manured with stable or 

 yard manure, made from cattle that are supplied with all the 

 salt they desire, thus receive more salt than is removed from 

 them in ordinary culture. 



25th. It is probable that thorough-drained fields will be more 

 benefited by (and require more ?) salt, than undrained fields 

 of similar soil. 



26th. It is a matter of experience, that while 500 to 600, or
