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.
