Much of their brief courtship had been spent in such wordless companionship: the man smoking beside her, with, or without, a book, while she worked; and he never wearied of watching that abiding miracle, a picture springing to life under an artist's fingers.

"You're not likely to give up this sort of thing, I suppose?" he asked suddenly; and she turned upon him with blank astonishment in her eyes.

"Give it up? . . . You might as well ask if I shall ever give up seeing, or hearing, or feeling. It is a part of me. You don't want me to give it up, do you?"

"Far from it. I was merely thinking that it seems suicidal for an artist of your quality to bury herself alive in a little Frontier station, on the edge of a desert, more than a hundred miles from anywhere."

"Rubbish! It simply means a new range of subjects for my brush. Tell me a little about it, please. I like to try and picture things in advance; and I am lamentably ignorant about this remarkable Frontier Force, to which I now have the honour to belong. Are we all on the wrong side of the Indus, always?"

"Yes, for ever and ever; except when we get away on leave."

"And then we go camping and climbing in the far hills beyond Kashmir, don't we?"

"Yes, invariably! For the rest of the time we keep 'cave' along six hundred miles of heart-breaking Border country."

"In other words, you are watch-dogs guarding the gates of an Empire?"

"That sounds far more imposing; and it's no less true. We are also actively engaged in helping the Indian Government to cultivate friendly relations with the tribes at the point of the bayonet!"
