As I was one of those who had observed the splendid meteor flash northwards almost under the face of the bright sun (at 10.25A.M), I sent the Professor a full account of what I had seen, for which he professed his strong obligations. This led to a very pleasant correspondence with Professor Herschel. After this, Idevoted considerable attention to meteors, and sent many contributions to 'The Observatory' on the subject.[4]
"You ask me what are the hours at which I make my observations?
I am due at the railway station at six in the morning, and Ileave at six in the evening; but I have two hours during the day for meals and rest. Sometimes I get a glance at the heavens in the winter mornings when the sky is clear, hunting for comets.
My observations on the sun are usually made twice a day during my meal hours, or in the early morning or late at evening in summer, while the sun is visible. Yes, you are right; I try and make the best use of my time. It is much too short for all that I propose to do. My evenings are my own. When the heavens are clear, Iwatch them; when obscured, there are my books and letters.
"Dr. Alexander Brown, of Arbroath, is one of my correspondents.
I have sent him my drawings of the rings of Saturn, of Jupiter's belt and satellites. Dr. Ralph Copeland, of Dunecht, is also a very good friend and adviser. Occasionally, too, I send accounts of solar disturbances, comet a within sight, eclipses, and occultations, to the Scotsman, the Dundee Evening Telegraph and Evening News, or to the Blairgowrie Advertiser. Besides, I am the local observer of meteorology, and communicate regularly with Mr. Symons. These things entirely fill up my time.
"Do I intend always to remain a railway porter? Oh, yes; I am very comfortable! The company are very kind to me, and I hope Iserve them faithfully. It is true Sheriff Barclay has, without my knowledge, recommended me to several well-known astronomers as an observer. But at my time of life changes are not to be desired. I am quite satisfied to go on as I am doing. My young people are growing up, and are willing to work for themselves.
But come, sir," he concluded, "come into the garden, and look at the moon through my telescope."We went into the garden accordingly, but a cloud was over the moon, and we could not see it. At the top of the garden was the self-registering barometer, the pitcher to measure the rainfall, and the other apparatus necessary to enable the "Diagram of barometer, thermometer, rain, and wind" to be conducted, so far as Coupar Angus is concerned. This Mr. Robertson has done for four years past. As the hour was late, and as I knew that my entertainer must be up by six next morning, I took my leave.
A man's character often exhibits itself in his amusements. One must have a high respect for the character of John Robertson, who looks at the manner in which he spends his spare time. His astronomical work is altogether a labour of love. It is his hobby; and the working man may have his hobby as well as the rich. In his case he is never less idle than when idle. Some may think that he is casting his bread upon the waters, and that he may find it after many days. But it is not with this object that he carries on his leisure-hour pursuits. Some have tried--sheriff Barclay among others[5]--to obtain appointments for him in connection with astronomical observation; others to secure advancement for him in his own line. But he is a man who is satisfied with his lot--one of the rarest things on earth.
Perhaps it is by looking so much up to the heavens that he has been enabled to obtain his portion of contentment.
Next morning I found him busy at the station, ****** arrangements for the departure of the passenger train for Perth, and evidently upon the best of terms with everybody. And here I leave John Robertson, the contented Coupar Angus astronomer.
Some years ago I received from my friend Mr. Nasmyth a letter of introduction to the late Mr. Cooke of York, while the latter was still living. I did not present it at the time; but I now proposed to visit, on my return homewards, the establishment which he had founded at York for the manufacture of telescopes and other optical instruments. Indeed, what a man may do for himself as well as for science, cannot be better illustrated than by the life of this remarkable man.
Mr. Nasmyth says that he had an account from Cooke himself of his small beginnings. He was originally a shoemaker in a small country village. Many a man has risen to distinction from a shoemaker's seat. Bulwer, in his 'What will He do with It?' has discussed the difference between shoemakers and tailors. "The one is thrown upon his own resources, the other works in the company of his fellows: the one thinks, the other communicates.
Cooke was a man of natural ability, and he made the best use of his powers. Opportunity, sooner or later, comes to nearly all who work and wait, and are duly persevering. Shoe****** was not found very productive; and Cooke, being fairly educated as well as self-educated, opened a village school. He succeeded tolerably well. He taught himself geometry and mathematics, and daily application made him more perfect in his studies. In course of time an extraordinary ambition took possession of him:
no less than the construction of a reflecting telescope of six inches diameter. The idea would not let him rest until he had accomplished his purpose. He cast and polished the speculum with great labour; but just as he was about to finish it, the casting broke! What was to be done? About one-fifth had broken away, but still there remained a large piece, which he proceeded to grind down to a proper diameter. His perseverance was rewarded by the possession of a 3 1/2 inch speculum, which by his rare skill he worked into a reflecting telescope of very good quality.
