OUR NATIVE BIRDS.

• TO THE EDITOR. Sir, —In a valley near Woodhaugh there are several tuis in fine plumage, and condition. There are also some bush wrens, or riflemen. At the.beginning of last week two pairs of the large size made nests, one. in a small pile of stones, and the other in a notch in a manuka tree, where a branch was broken off. There were two eggs in one. and one in ■ the other. But-cold and bleak rainy weather, with the shortage of food, forced the little birds to abandon tbeir nests. It would be a good idea if nests wereplaced for the native birds as in the United States. One. plan is for the holebuilders to hollow out a block of round wood with the bark on, and fasten moss all round it, and fasten it on to a tree.— I am, etc., Richard Norman, December 1.

When the wind blows do the American skyscrapers sway?; The swing of a 555 ft skyscraper in Ohio has been scientifically measured and pictured by what the experimenters call a “sway photom.” It consists of a steel rod, to which a small light is attached, suspended from the wall at the thirty-seventh floor, and a camera attached rigidly to the floor. The camera moves with the building, but the light remains stationary. As yet no results have been tabulated.
