"It sounds like a police court case," she said sadly. "'Lallie Clonmell, having no visible means of subsistence, and giving no address, was yesterday arrested as being of "disorderly personal habits."' Well, Tony would come and bail me out if the worst came to the worst. And yet I'm considered very tidy and managing at home; quite a sort of Mrs. Shakespeare, in fact. Everything depends on environment."

Miss Foster made no answer. Literally and figuratively she had wrapped herself up in the Spectator.

But the harp, the piano, the bits of cotton dropped on the floor were mere venial offences compared to the sin of making dirty footmarks upon the stair carpet.

The front staircase at B. House is imposing, wide, and Y-shaped. The first broad flight of steps starts from the centre of the large square hall. Half way up it branches into two, terminating at opposite ends of the landing upon which open the chief bedrooms, and the assistant-master's sitting-room. It is a handsome staircase of polished oak--no other house in Hamchester College has one half so fine--and it was at that time carpeted with a particularly soft and thick, self-coloured, art-blue carpet that matched the walls.

When the master of the house found how conspicuous were muddy or dirty footmarks on this same carpet, and how such defacement distressed Miss Foster who had chosen it, he always used the boys' staircase whenever he went to his room to change. So did Mr. Johns. Till Lallie came no one save Miss Foster ever used the front staircase at all, and she was most careful never to ascend by it if her boots were either muddy or dusty. She therefore saw no reason why Lallie should not show equal forethought, especially as there was no chance of her guest meeting any of the boys on the back staircase, as they were never allowed to go up to the dormitories during the day.

Alas! Lallie showed no disposition to consider the welfare of the carpet, but ran lightly up to her room by the front stairs no matter how dirty her boots, and she often left the clear impression of a small sole on every step.

The third time this occurred Miss Foster met her just outside her bedroom door, and remarked with some acerbity:

"Haven't you discovered the other staircase yet, Miss Clonmell? It really is the shortest way to your room."

"I like these stairs best, thank you. I'm not used to wooden stairs; my feet make such a patter it disturbs me."

"But look at the marks your feet have made on the carpet," Miss Foster expostulated indignantly.
