She got a long stick to put under it to hold it up, and then tried to climb in.
She found, however, that the window sill over which she was to climb was still rather too high; but, at length, after various consultations and experiments, _Bella_ succeeded in getting up by means of the help which Mary Bell, who was large and strong, gave her, by "boosting her," as she called it, that is, pushing her up from below while she climbed by means of her arms clasped over the window sill above.

Bella being thus in the house, took the key, which Mary Bell handed her for the purpose, and went along to the entry to unlock the door, while Mary Bell, stepping down from the scaffolding, went to the door on the outside, ready to enter when it should be opened.

The children had no doubt that there was a key-hole in the lock on the inside, although there was none made in the door on the outside.
When, however, Bella reached the door on the inside, she called out to Mary Bell, through the door, to say that she could not find any key-hole.
"It is in the lock," said Mary Bell.
"But there is not any lock," said Bella.
"Is not there any thing ?" asked Mary Bell.
"Yes," said Bella, "there is a bolt." "Oh, very well, then, open the bolt," replied Mary Bell.
After a great deal of tugging and pushing at the bolt, Bella succeeded in getting it back, but even then the door would not come open.

It was new, and it fitted very tight.

Bella said that Mary Bell must push from the outside, while she held up the latch.
