"Such things will come to pass, before many years are over, as are little dreamt of now, and all through your wanting to swallow that dose of cyanide at No. 36 Rue des Ursulines Blanches, and my having the gumption to prevent you! "It's a good seed that we have sown, you and I. It was not right that this beautiful planet should go much longer drifting through space without a single hope that is not an illusion, without a single hint of what life should really be, without a goal. "Why such darkness under so bright a sun! such blindness to what is so patent! such a deaf ear to the roaring of that thunderous harmony which you call the eternal silence!--you of the earth, earthy, who can hear the little trumpet of the mosquito so well that it makes you fidget and fret and fume all night, and robs you of your rest. Then the sun rises and frightens the mosquitoes away, and you think that's what the sun is for and are thankful; but why the deuce a mosquito should sting you, you can't make out!--mystery of mysteries! "At the back of your brain is a little speck of perishable matter, Barty; it is no bigger than a needle's point, but it is bigger in you than in anybody else I know, except in Leah; and in your children it is bigger still--almost as big as the point of a pin! "If they pair well, and it is in them to do so if they follow their inherited instinct, their children and their children's children will have that speck still bigger. When that speck becomes as big as a millet-seed in your remote posterity, then it will be as big as in a Martian, and the earth will be a very different place, and man of earth greater and even better than the Martian by all the greatness of his ampler, subtler, and more complex brain; his sense of the Deity will be as an eagle's sense of the sun at noon in a cloudless tropical sky; and he will know how to bear that effulgence without a blink, as he stands on his lonely summit, ringed by the azure world. "Indeed, there will be no more Martians in Mars by that time; they are near the end of their lease; all good Martians will have gone to Venus, let us hope; if not, to the Sun itself! "Man has many thousands of years before him yet ere his little ball of earth gets too cold for him; the little speck in his brain may grow to the size of a pea, a cherry, a walnut, an egg, an orange! He will have in him the magnetic consciousness of the entire solar system, and hold the keys of time and space as long and as far as the sun shines for us all--and then there will be the beginning of everything. And all through that little episode in the street of those White Ursulines! And the seed of Barty and Leah will overflow to the uttermost ends of the earth, and finally blossom and bear fruit for ever and ever beyond the stars.
