Sir - Malcolm Graham, arguing that Bonn Square should be left as it is (February 16), referred to the 'mature trees' as 'an attractive feature'.

The architects responsible for the new scheme admit that they are healthy, but say that they are 'out of scale with the space' and 'lack visual coherence'. This absurd remark presumably means that they are not - like the trees in their scheme - small and arranged in a straight line. Readers of The Oxford Times scarcely need to be reminded how many trees have recently been lost in Oxford. These are being sacrificed in favour of a CCTV-friendly desert.
