Two minor updates to the list of sources of magic knight tours of the standard chessboard have come to light from my researches in Le Siecle.
Tour 00i by an Unknown composer appears as problem 772 on 25 April 1979 with solution on 2 May 1879. The word puzzle used with it is given as by M. Jacquemin-Molez but the composer of the design is not identified. The column is signed as by A. Feisthamel as usual, but if by him the designer would probably be cited as M. A. F. so I think we have to classify it as still Unknown and from an earlier source. The 1879 date is one or two years earlier than the 1880/81 date given by Murray.
Tour 00f by Palamede (the pseudonym of Count Ligondes) appears as problem 2134 on 31 August 1883 with solution on 7 September 1883. There does not seem to be any mention of its cyclic properties.

Magic Square in Figured Tour
In my booklet on Figured Tours published in 1997, there is a knight's tour, A5 on the 8x8 board in which the first nine even numbers form a magic square. The tour is by T. R. Dawson and originally published in Vie Rennaise 19 November 1932. It led me to wonder if the same task could be done on a smaller board of minimum size.
The 3x5 board with a cell added at the middle of each side is of 19 cells, that can be chequered to show 9 dark cells in the form of a diagonal square and 10 light cells. Unfortunately this board has no knight tour, for the same reason as the 3x5 board, formation of a closed path firmed by the knight moves available at b3 and f3.
However if the extra cells are added on the long sides to form a rotary symmetric board as shown below the board becomes tourable. In fact there are 62 symmetric tours. Among these there are just six in which the square formed by the even numbers is magic. As shown here:
I wonder if this result can be new?

National Chess Library
Since September last year I have been travelling weekly by bus to Battle to help with the arrangement of the National Chess Library books on the shelves. The Library is now in the Offices of the English Chess Federation at the Watch Oak. Here is a plan I made of the current arrangement of the subjects on the shelves.
The Library is made up of a number of separate collections, the largest of which are the ECF's own collection and that from Harry Golombek. The books are labelled to show which donor collection they are from, and are now mostly arranged on the shelves by subject rather than collection. Because of the way the Library has accumulated there are many duplicates. Duplicate periodicals are being stored in the loft and duplicate books are on the bottom shelves. The Library is open for visitors, but the offices are closed at week ends.

Catching Up
I can't seem to keep up regular posts here.
On 12 July I went into Eastbourne Hospital expecting to have an operation, but after discussion with the surgeon it was decided to postpone it for further tests that are now due on 18th October.
On 15 July I went to a l0cal chirch, St John's Brittany Road, for a concert by Hastings Sinfonia. I tweeted that they should be called sinfffonia since they were far too loud for me. On 16 Juky I went to Eastbourne for a concert at the bandstand. That was more enjoyable. So much so that I went to several other band concerts there on other Sundays. Always preceded by fish and chips. My brothers also came for a meal on the 23rd but didn't stay for the music.
In August 18th to 20th I went to play in the Minor section of the Thanet Chess Congress. However I could only manage three draws against weaker opposition, which decided me not to renew my membership of the Hastings Chess Club in September, having taken a rest from it last year.
During the week beginning 11 September I went to Battle to help with putting the National Chess Library on shelves that had been installed in the English Chess Federation offices there. Good progress was made, though there are still some further bookcases to be set up.
Because I had been thinking of moving back to the midlands, I took it into my head to order a mobile phone. However while chasing after the DRD delivery driver, who was trying to deliver the parcel to the wrong address, I missed the bottom step and slipped, spraining ankle. Later I also returned the phone since I couldn't work out how to use it. So not a happy time.
More updates to come.
