Mr. Mahlon Carver, of Carversville, Bucks co., Pa., writes: " I have thought for years there should have been more progress in bringing new varieties of fruits, plants and cereals than by the slow, uncertain force of admixture of pollen. While all other arts and sciences have made wonderful strides, we follow the same old routine, and the world . has no such wonders as history tells us existed in the Hanging Gardens of Babylon, the Garden of Solomon, or beauties of Saracen conquest of Grenada in groves and gardens. In looking over the great changes in insect life and witnessing their wonderful transmutations, and noting the great assimilations of animal and vegetable minute organism, I am led to advance the theory of heart hybridizing, or changing and bringing out new improved forms by heart admixture. The first principle or life force spring's from the heart; this is the first vital force in all animated existence. Nature furnishes a life-concentrating alloy in propagating species, to concentrate and give vitality to first implanted life germs in all varieties. You notice the great mission of insect life that renews life force by mixing the pollen of diverse varieties.

What can be brought out to bless the human race, if my theory should prove correct, time and close experiments, patience and skill, will only determine. I feel sanguine of great results in time. I will in conclusion give the manner of conducting experiments, hoping you with your more extended experience and greater knowledge will suggest a wiser plan: Firstly, to hybridize wheat and rye, or oats and barley, take an equal number of grains of each variety, soak in warm water until they begin to germinate, then with a sharp thin instrument cut them in halves, put the half of each variety together - heart ends together - secure with mucilage or some life-giving alloy, and plant. I believe the plum and peach, the walnut and chest nut, and the shellbark and acorn, can be changed into new forms to beautify the earth and bless humanity. Excuse the liberty I have taken of trespassing on your time and patience. I hope you will give the subject your kindest consideration, and spare me a word of encouragement if you deem my theory worthy of further favor".

[The best encouragement we can give our friend is, to try it himself. If any one else cut the half of a peach kernel across and graft the half of a cherry kernel on to it, and get a new hybrid fruit from it, our friend will be sure to come forward and claim the honor of making the first suggestion, and it would be an honor indeed! But how much more honorable would it be for our correspondent to do the thing himself. It is extremely disinterested in him to give away so grand an idea, but we are sure few of our readers will want to profit by it at his expense, and will agree with us that in a matter so easily tried, it will be only fair to let our correspondent have the full credit that may follow the successful experiment. - Ed.
