The Certainty of a Future Life in Mars / Being the Posthumous Papers of Bradford Torrey Dodd

by L. P. Gratacap

To me whose emotional nature, inherited from a mother gifted with delicate tastes and a refined enthusiasm for the beautiful had been curiously discouraged by association with my father's scientific pursuits, this lively panorama constantly fed my dreams with pleasing pictures.

My life has been an isolated and repressed one, except for the one incident I am about to bequeath to posterity. I had not enjoyed the play of youthful companions except in a fugitive way, I had not gone to school nor passed three years of muscular and buoyant activity in the usual pastimes and pleasures of childhood. I had a precocious nature and it had been unfolded in an atmosphere of strictly intellectual ideas. My mother had been a constant joy to me during the short years of her life on earth, but somehow by reason of sickness I had not enjoyed even her endearment as I might have.

So in my father and his aspirations, and the later hopes of his excited and passionate longing to regain some trace of my mother, my life from four years of age was actually and potentially concentrated. My father cherished me with a great consuming love. He saw in me the representation in face and partially in temperament of his wife. He lavished on me every care. Yet because of his eager affection, and his complete suspense from social connections I was made too largely dependent on him alone. I lived in his companionship only. My conversation became prematurely advanced in terms and principles, and my childish confidence was nurtured by nothing less wonderful than books and theories, experiments and dissertations.

The wonderful beauty of our new surroundings, the strangeness of our sudden removal from America, the long distances travelled, awoke in me new thoughts and I readily surrendered myself at times to the incoherent struggles of my nature, to find someone, something, more responsive to my young feelings than essays on magnetism, and a man, father though he was, immersed in demonstrations and problems. It was then that this distant picture in the days of the fragrant and reviving springtime, filled me with unutterable and touching ecstacy.

My father, as I had said, fully intended to arrive at some definite conclusions as to the possibilities of wireless telegraphy. At one end of the grassy plain I have alluded to, our chief stations were erected and, at the distance of two miles, almost at the other extremity, we placed a smaller station. Our whole work was to achieve telegraphic communication between these points without wires. At night my father bent his telescopic gaze upon the heavens, and as the earth approached opposition to Mars in 1884 I remember his eagerness and his repeated adjurations that if we failed in the task in his lifetime I should devote my life, separated from all other occupations and indulgences, to carrying on his designs.

At first he only dimly intimated his great ambition, the union of our world with others by magnetic waves, but as it slowly assumed a theoretical certainty he talked more and more boldly of this portentous and transforming possibility.

I cannot refrain from noticing another important scientific activity of my father's. It was the use of photography in stellar measurement. As is well known to photographers, in 1871 Dr. R.L. Maddox used gelatine in place of collodion from which innovation rose the present system of dry plate photography. My father had always felt the greatest interest in the use of photography in astronomy. He was acquainted with the splendid work done by Chapman for Rutherford, New York, in his careful and exquisite photographs of the moon. As early as 1850 Whipple of Boston made photographs of the stars.

It was, however, the incomparable advantages, furnished in speed, by the dry plate photography which made my father realize early as anyone, the boundless possibilities thus opened in human attainment for the penetration of the Sidereal firmament. He had made a great number of photographs at Irvington, and the photographic laboratory was a charming illustration of my father's ingenuity and precision. At Mt. Cook we enjoyed a marvellously clear atmosphere for work of this sort, and amongst the first thoughts of my father was to provide the most satisfactory means for the continuance of our stellar photography. Besides our visual telescope we had a photographic telescope which was used, instead of connecting the visual lens on one and the same instrument, as in the Lick Observatory.

The innovations introduced by photography have revolutionized the processes of stellar measurement. Instead of the laborious task of measuring the stars through the telescope, the photographic plate can be studied at ease as a correct and identical chart of the heavens and the results thus obtained placed at the disposal of astronomers. My father appreciated this and amongst his numerous projects of scientific usefulness the preparation of photographs of the stars fully occupied his mind.

We had no Meridian Circle, as it was less in the direction of the determination of the position of stars than in the elucidation of the surfaces of planets, that my father's astronomical predilections lay. Our telescope was a refractor and had an objective of two feet diameter. It was firmly supported on a trap rock pedestal. The eye piece adjustment was unusually successful, and the remarkable freedom of the objective from any traces of spherical or chromatic aberration gave us an image of surprising clearness. The photographic results were admirable. I imagine few more satisfactory photographs of the face of Moon have been made than those we secured, so far at least as definition is concerned, and the detail within the limits of our powers of magnification.
