When Saunders Wanted a Change Bishop Doane, of Albany, who is keenly interested in the abolition of the divorce evil, paused for a moment, in an earnest discussion of divorce, to narrate a pat anecdote.
"The motive of these people," he said, "is like the motive of a Scot who was found weeping one day by his comfortable hearth.
“ 'Eh, Saunders, mon,' said a neighbor, peeping in at the open door, attracted by the sounds of woe, 'what's ailin' ye?'
“‘Oh, dear; oh, dear,' sobbed Saunders, ‘Donald Mackintosh's wife is dead.'
“ Aweel,' said the neighbor, 'what o' that? She's nae relation o' yours.'
“I ken she's no',' wailed Saunders. “I ken she's no'. But it just seems as if everybody's gettin' a change but me.' "

Sprays Huge Tube THE accompanying illustrations show
a machine used in whitewashing a London tube railway. E. P. Grove, head engineer of the Central London Railroad, conceived the idea that the tunnel would be better illuminated if the walls were whitened so as to diffuse the light. The ordinary paint-spraying machines, he decided, would not perform adequate service, as the maker could not meet his exact requirements. With some changes, he has found what he wanted in a machine used for washing hop-fields. The nozzles of this have been increased to forty in

A big baking oven supplies fresh bread daily, and the huts are lit with electric light, for which power is obtained from the waterfalls. There is even a small emergency hospital, and minor accidents are treated by the senior engineers.
Among the best known of the scenic railroads of Switzerland are the Rigi, whose summit commands a 300-mile panorama; Pilatus; the Brunig Pass; the Bernese Oberland ; the St. Gotthard itself, which cost $52,400,000; the Gornergrat of Zermatt; the Albula, one of the latest of all; the Mont Salève; and the Rochers de Naye.
