POINTS FROM LETTERS WIRELESS FOR THE BLIND.

Will you allow me space in the Spectator to thank all those kind readers who have shown their practical sympathy in my four years' pioneer effort to get a National Fund for Wireless for the Blind ? If only those who find pleasure and entertain- ment in their own wireless realized the joy the wireless is to those blind people who have now a set installed by their own fireside there would be few pining for one to-day !--STEwART RoYsrox, Sunnyside, Paddington, nr.

TREE-PLANTING.

Mr. Ensor's articles on tree-planting in the Spectator are most interesting; but though it is presumptuous of an amateur with only practical experience of forestry to criticize an expert, may I say he is a little misleading ? Trees are to be chosen "thirdly, not to let us down by succumbing to gales" and then he goes on to advise in the first flight Cupressus macrocarpa and in the second Pinus insignis. These two species are thought by many nurserymen to be the worst rooters there are ; and certainly here have lived up to their reputation • or rather blown down to it ; and of clumps of both planted some twenty-five years ago about a quarter have been blown down. Of Douglas fir I endorse all he says, except that in Angus, where It does exceptionally well, it is often outdistanced by the very beautiful Sitka spruce (Picea Sitchensis) which has the added merit of being almost rabbit proof. Two other very fast growing trees in Angus are the silver Irobilis, and the Albertiana hemlock spruce (Thuja Albertiana).—(Miss) EVELYN Murat°, Fairfield, Lyme Regis.
