R.M.S: Anselm
Tuesday, March 11 | 1919

My very dear Mother

We are now approaching Lisbon and expect to arrive soon after daylight tomorrow morning. The weather has been pretty good; it was warmest on Sunday, which was a beautiful sunny day, and one could sit out on deck chairs without an overcoat. Yesterday and today, there was more wind and occasional showers. It has not been very rough, but there was sufficient motion to make a good many of the passengers unhappy. Of our party, Crommelin & Cottingham succumbed for a time, but they both seem much better today.

We all arrived at Euston an hour-and a half before the train started; but it took a good while to deal with our bulky luggage. We were charged 30/– excess, but most of that was for the object-glasses which being labelled “glass” were charged at a higher rate. We got to Liverpool at 3∙45 and then difficulties began. The Hotels were full and there were scarcely any porters at the station. At last we found a porter of a baggage agency, and put all except our handbags in his charge to deliver to the Steamer. Then we set off in a taxi to hunt for a Hotel. After 3 or 4 attempts we got in at quite a comfortable commercial hotel. I think we were probably very lucky. It was a pouring wet night, so we did not go out.

The next day we got down to the dock about 10 a.m. Our luggage was promised for 10∙30 a.m.; but did not arrive. Soon after 11 we had to go on board, because the emigration officer was only there for a short time. He just looked at the passports and did not worry about anything else. We were not very anxious about the luggage because we soon found about a dozen other passengers were in the same plight as ourselves having entrusted their luggage to the same firm. Ultimately about 12∙30 it all turned up, and we went down to lunch, much relieved.

The Anselm is a very nice boat, and seems much roomier than I expected. I should think there are at least sixty first-class passengers on board. Our cabin is nicely placed, a good height above the water, and is very quiet. Davidson & Crommelin are next door. It seems curious to have done with rationing entirely—unlimited sugar, and large slices of meat, puddings with pre-war quantity of raisins & currants in them, new white rolls, and so on.

We left at about 2 p.m. and went slowly through a chain of docks to the Mersey. One of the Directors of the Booth Line was on board at the start and saw us for a few minutes. We saw the lights of Holyhead about 9 p.m. and stopped a few minutes to drop the pilot. Since then we have seen no land whatever, and have had only very vague ideas as to our position; there is still a war-regulation which forbids them letting us know where we are & what our course is.

Davidson & Crommelin had to sit at the Captain’s table, so our party was broken up. It is supposed to be a special favour to be asked to sit there; but as they are too far from the Captain to get to know him, it does not seem much good. There is one other passenger whom I knew through correspondence, Mr. Walkey an amateur astronomer. He is going out for the Bible Society to live on a house-boat on the Amazon travelling up and down the various tributaries. He expects to be out there most of his life.

I have had a few games of chess with Crommelin and also with a Frenchman, have read a bit, and passed the time very comfortably. I am quite glad to be having a long steamer trip again.

With very dear love from
your affectionate son
Stanley

Dear Mr Eddington,

May I ask you—in confidence—whether you consider yourself definitely fixed to “Astronomy” or whether you would at all consider a return to Physics as possible.—I am not at liberty to go into details but the question arises whether in case a chair of Theoretical Physics were founded here or elsewhere and suitable conditions were offered you would be prepared to accept the chair.—Also in that case it might help matters if you wd let me know what conditions you would consider acceptable.

You may take it for granted that the duties wd leave you plenty of time for private work and that nothing wd prevent you continuing to prosecute the line of research on which you have entered with such success

I remain
Yours sincerely
Arthur Schuster.

Grand Hôtel des Bergues, Genève
3. Jan 1898.

Dear Mrs. Eddington,

I sent you just one bit of my ideas abt. Stanley as soon as he left us. The rest must follow now.

His presence has been a great pleasure to us. You have got a boy mixed of most kindly elements, as perhaps Shakspeare might say {1}. His rapidly and clearly working mind has not in the least spoiled his character. I don’t know when I have had to do with so modest and gentlemanly a boy. It is a testimony to day schools and home training, (not, I am afraid, my favourite theory.)

His youth has, of course, been just a little against his making friends, but has not been fatal to it. In Clayton, & in Wood & Brown he has nice associates; but he seems more contented alone than most boys are.

His work is all that I expected, & more: & I feel altogether that he is “a precious youth” committed to my charge. I can realise to some extent what Margaret would feel like if she were left alone to bring up our own little Richard.

I remain
Your friend sincerely
John W. Graham

—————

The writing-paper is engraved with illustrations of the hotel, etc. The year is wrong, as Eddington did not enter Owen’s College till October 1898 (see his Notebook).

{1} Graham evidently had in mind Antony’s encomium on Brutus at the end of Julius Caesar: ‘His life was gentle, and the elements | So mix’d in him that Nature might stand up | And say to all the world “This was a man!”’
