We like the straight-forward spirit of Mr. Gowkn's remarks, and find by them, that in the main point at issue we are entirely agreed'That is to say, if Mr. Gow-in simply wishes to affirm that there is no comparison in the value of barn-yard manure for keeping a farm in heart, and green crops, we say Amen, with all our heart. No person has a firmer faith in the value of barn-yard manure, than ourself, as we believe that with plenty of it, and the knowledge how to use it, one might smile, even at the bottom lands of the west. But, as Mr. Gowrk will not deny, that the said bottom lands are the most fertile lands in America, will he do us the favor to ask himself how they became such a store house of fertility? By the deposit and decay of animal remains? No. By the annual deposit for hundreds of years, of vegetable remains? Assuredly. Nature has been plowing in green crops every year, on those bottom lands, till they are most undeniably rich.

So far we think Mr. Gowen" will agree with us - that there is virtue in decaying and decayed vegetation buried in the soil, whether in the shape of clover plowed in or other wise. But we now suppose from reading his remarks, with which he has favored us, in the above communication, that we have probably misapprehended him in another way. Mr. Gowen is not only a good practical farmer, but an excellent teacher of husbandry, and in Pennsylvania and the states south of it he notices that farmers neglect their barn yard manure to follow the new fangled fancies of plowing in green crops, using mineral manure, Ac. He accordingly tells them that green crops, under such circumstances, are not worth their attention,, which ought to he devoted to the permanent enrichment of their lands by the use of animal manure. And the advice is the best of advice. We look upon barn yard manure as the solid bullion, green crops, gypsum, lime, etc., as the paper currency of husbandry. But in many parts, we were going to say most parts of the country, the bullion is scarce - is only to be had in very limited quantities - so that not a half or third of the farm lands can be welt manured with it.

In such a condition of things a farmer who wishes to mend his land and not lose his profit, will, we think, occasionally employ the paper currency to maintain and restore the credit of certain fields that would come to a beggared condition, if they had to wait for the bullion. Barn yard manure, we say with Mr. Gowen, before everything, but if we can't get enough of it, then we must not despise what the experience of so many good husbandmen has proved of decided benefit - green crops ploughed in.
