of ice in another, is worthless, or next to worthless, in regions 

 where they are produced, and yetareof inestimable value in those 

 regions where these sub.-tances are not produced, for tempering 

 the composition of men. A perfect commerce, one that shall 

 completely diffuse and blend together the different productions 

 of the different regions of the earth's surface, so that men may 

 choose completely their diet, and fully exercise their inventive 

 powers in new combinations of the raw material of things, is a 

 necessary physiological requisite to the advent of the " coming 

 man." Such natural circumstances must attend the incarnation 

 of this myth of ours, and we are not to expect him until a perfect 

 communication shall have been established with the different 

 nations of the earth. 



Prof. Mapes — Lime is mistaken as a manure. It is not so. 

 Plants contain lime, but the use of it in agriculture is not properly 

 a manure. But it is a decomposer of vegetable matter and manu- 

 facturer of manure. Thus wood is rendered pulverulent by lime, 

 and fitted as pabulum for plants. It requires 700 lbs. of water to 

 dissolve one pound of lime. However minute the quantity of 

 lime in soils, the plants will find all that is required in their 

 structure. Turnips need lime, yet they are 93 to 97 parts water, 

 hence the quantity of lime must be very small. It plays the part 

 of forming all the salts required by plants. It will fit phosphorus 

 for food for growing plants. Free chlorine is seized hold of by 

 lime in the oil. Where it is used largely upon soils full of am- 

 monia, it does more harm than good, because it sets the ammonia 

 free ; hence it should never be used upon manure heaps. Salt 

 is useful and necessary in the growth of plants. Beginning with 

 a mixture of salt and lime, we end with chlorine and carbonate 

 of soda, which absorbs and retains ammonia. Lime travels down 

 through the soil as far as it is plowed ; hence it should always be 

 placed upon the surface. Wiien land has been limed many years, 

 a deepening of plowing is often equal to a new dressing of lime. 

 Sow dry salt, from six to twenty -five bushels per acre, it will kill 

 grubs. You should not throw it on rows of potatoes, but between 

 them, to kill grubs. A small quantity of salt will hurry the 

 decomposition of muck heaps. Mr. Dodd, of Newark, says, that 

 the lime and salt mixture around peach trees will kill peach worms.
