Those who try honestly to find out how the discoverers of new trees, flowers or fruits may reap the benefit of some just legal protection such as discoverers in the arts receive through the patent office, must expect to be indecently abused, should their careful conclusions not happen to agree with those of some others. Our readers may remember the billingsgate effusions sent to the editor, some of which at the call of "justice to the cause," we felt compelled to inflict on the reader. Dr. Warder and Mr. Parker Earle are now feeling the arm of vengeance. It appears that the Mississippi Valley Horticultural Society appointed a committee to examine this subject. They evidently found it to be surrounded by difficulties, and instead of reporting against it at once, took time to consider these difficulties. One "of our number," to wit: Mr. Jacob Moore Samuel Miller, S. Rommel, J. H. Ricketts, Wm. Culbert, wrote to Dr. Warder to know the reason, and received the following reply :

"Our committee on plant protection had consultations, and reported that as yet we felt unprepared to make any recommendations for the action of the Society. I think the chairman felt we could do nothing".

This civil reply was, however, enough to raise the angry passions of " our number," and with their names and addresses in full they have issued a bill of excommunication to Mr. Parker Earle, from which we take the following sweet morsel:

"We had hopes that the Society of which you are President, founded as it was to promote advancement in horticulture, would on that account advocate our cause ; but thus far, we are sorry to say, these hopes have not been realized.

" History shows that truth of vital importance to mankind, has often met with the strongest opposition from those who should have been the first to receive it. The well-known hostility of Dr. Warder, if not of yourself to the protective measure, which is destined to advance American Horticulture beyond, and above that of all the other nations of the earth, is a recent exemplification of such opposition to progress".

The great comfort these gentlemen must derive from all this is, that as they seem well versed in history, and familiar with its truths, they were not very much surprised when they found history merely repeating itself. We are willing to believe that at least one of those whose names are attached to this document did so without weighing its scandalously abusive character.
