I firmly believe that great results of signal beneficence are to be slowly but surely achieved by means of the household convenience known as the Earth-Closet, and by kindred devices for rendering inoffensive and utilizing the most powerful fertilizer produced on every farm and in every household. That is a vulgar squeamishness which leaves it to poison the atmosphere and offend the senses on the assumption that it is too noisome to be dealt with or utilized. A true refinement counsels that it be daily covered, and its odor absorbed or suppressed by earth, or muck, or ashes, and thus prepared for removal to and incorporation with the soil. It is far within the truth to estimate our National loss by the waste of this material at $1 per head, or $40,000,000 in all per annum: a waste which is steadily diminishing the productive capacity of our soil. This cannot, must not, be allowed to continue. We must devise or adopt _some_ mode of securing and applying this powerful fertilizer; and I defer to that which is already in extensive and daily expanding use. Let whoever can do better; but meantime let us welcome and diffuse the Earth Closet. XXI. MUCK--HOW TO UTILIZE IT. The time will be, I cannot doubt, when chemists can tell us the exact positive or relative value of a cord of Muck--how this swamp or that pond affords a choice article, while the product of another will hardly pay for digging. There may be chemists whose judgment on these points is now worth far more than mine, since mine is worth exactly nothing. I _do_ know, however, that Muck is a valuable fertilizer, and that digging and composting it _does pay_. I judge that I have transferred at least three thousand loads of it from my swamp to my upland; and the effect had been all that I expected. Let me speak of Muck generally, in the light, of my own experience.
