"While sending you the enclosed communication,"says" L. G.," " I feel like criticising the editor in his view that tree trunks do not elongate, but 1 know the rule in editorial work that correspondents may be allowed to criticise one another, but that the editor's decision must not be questioned." Our correspondent is mistaken in regard to the editor of the Gardeners' Monthly. We have no such editorial pride of infallibility. The editor is just as likely to get wrong as a correspondent, and well-intentioned criticism is welcomed rather than repressed.
