"I began to have a wish for a telescope, by means of which I might be
able to see a little more than with my naked eyes. But I found that I
could not get anything of much use, short of 20L. I could not for a
long time feel justified in spending so much money for my own personal
enjoyment. My children were then young and dependent upon me. They
required to attend school--for education is a thing that parents must
not neglect, with a view to the future. However, about the year 1875,
my attention was called to a cheap instrument advertised by
Solomon--what he called his '5L. telescope.' I purchased one, and it
tantalised me; for the power of the instrument was such as to teach me
nothing of the surface of the planets. After using it for about two
years, I sold it to a student, and then found that I had accumulated
enough savings to enable me to buy my present instrument. Will you
come into the next room and look at it?"
I went accordingly into the adjoining room, and looked at the new
telescope. It was taken from its case, put upon its tripod, and looked
in beautiful condition. It is a refractor, made by Cooke and Sons of
York. The object glass is three inches; the focal length forty-three
inches; and the telescope, when drawn out, with the pancratic eyepiece
attached, is about four feet. It was made after Mr. Robertson's
directions, and is a sort of combination of instruments.
"Even that instrument," he proceeded, "good as it is for the money,
tantalises me yet. A look through a fixed equatorial, such as every
large observatory is furnished with is a glorious view. I shall never
forget the sight that I got when at Dunecht Observatory, to which I was
invited through the kindness of Dr. Copeland, the Earl of Crawford and
Balcarres' principal astronomer.
"You ask me what I have done in astronomical research? I am sorry to
say I have been able to do little except to gratify my own curiosity;
and even then, as I say, I have been much tantalised. I have watched
the spots on the sun from day to day through obscured glasses, since
the year 1878, and made many drawings of them. Mr. Rand Capron, the
astronomer, of Guildown, Guildford, desired to see these drawings, and
after expressing his satisfaction with them, he sent them to Mr.
Christie, Astronomer Royal, Greenwich. Although photographs of the
solar surface were preferred, Mr. Capron thought that my sketches might
supply gaps in the partially cloudy days, as well as details which
might not appear on the photographic plates. I received a very kind
letter from Mr. Christie, in which he said that it would be very
difficult to make the results obtained from drawings, however accurate,
at all comparable with those derived from photographs; especially as
regards the accurate size of the spots as compared with the diameter of
the sun. And no doubt he is right.
