We are altogether in the novitiate as yet in the United States, so far as much progress in this respect is concerned. What with getting a living, clearing up the forests, subduing the land, getting avenues to market, and looking out for the main chance, we have had but little time to look into the great secret store-houses of nature, and closely examine her beautiful and elaborate processes of improvement. What we have discovered in this line, has been chiefly blundered into by accident; and if we have had any men among us who occasionally devoted any amount of mind to investigation, and published their results to the world, it has been in the ephemeral papers of the day, and in the usual skimble-skamble reading of such as ought to have been instructed by it, the essential benefit has been lost. But thanks to the late encouragement of hooka and publications set apart to subjects of vegetable physiology, growth of plants, new varieties of fruits, Ac., Ac., we may now begin to date some real progress in this line. Every thinking mind will subscribe most cordially to the sentiments of the article in question, which is truth, concisely, cogently, and plainly set forth.

You remark: " we are not going to be led into a physiological digression on the subject of the inextinguishable rights of a superior organisation in certain men and races of men, etc." Very well, Mr. Editor, you may not, but I am. And you no doubt perfectly agree with me, as every body else will, who has the candor to confess it. There is as much difference in the breed of folks, as there is in the breed of pigs and chickens, or in the different varieties of vegetables. Look at the despotisms of the old world, where men are dirided into castes, or from the force of circumstances, obliged to more for generation after generation, in one continned sphere of thought and action, from father to son, interminably on, and see how men, under such circumstances, are born and made to differ, although of one original stock. Look how particular traits of talent run in different families for many generations, even in this country; and if, after a while bred out by intermixture with blood of a different "gift," the peculiar faculty will occasionally creep out, and act with its ancient energy and aptness. So in personal appearances and peculiarities.

I consider that our " democratic" tendencies are fast infusing the levelling system among us, either up or down, as the case may be; but as we become better physiologists in the animal world, as well as in the vegetable, we shall fully understand it. I am aware that I am travelling somewhat out of the record, but the idea is suggestive, and it will do no harm to direct attention to it, even in these pages.
