A correspondent writes that we are wrong about the postal laws on seeds and plants; that the obnoxious express rates of last season have been repealed, and that his postmaster receives things from him at the rate of one cent for two ounces.

Notwithstanding all this, we assure our correspondent that the Express companies' law of last season is not repealed, and that post-master of his his may get him and himself into trouble one of these days. More than this, we do not believe the people are strong enough to defeat the Express companies in this matter. They can afford to keep men at Washington to explain their side of the case; the People have no representative. We do not believe the stories of the sensational newspapers that members of Congress are bought up to vote in these and other instances. These men, many of whom we know, are as honorable as any other body of men, and such charges are as a rule, but the outpourings of spite and evil dispositions; but we mean that plausible arguments and representations on one side against little or nothing, on the other, are bound to tell in the long run, and this is the advantage the companies have over us all. Even more, it may after all be good national policy, as well as to the advantage of the Express companies, to have the law as it is, but so far as we understand, it does not seem so.

If any of our readers have undoubted facts and figures to bear on this question we would willingly publish them, and we think a good tempered article in our columns would have weight at Washington. We do not want mere newspaper statements or newspaper figures; these can be made to prove any side. But what is wanted is to show that mailing seeds, cuttings, plants, etc, is not merely a benefit to horticulture, but is no serious loss to the Post-Office Department.
