A thought came into her mind that she might ride across to Blow End, where their nearest neighbour lived, and ask her to go over to Duck Flats and stay with poor Tom until she got back again. But second thoughts decided her against it. Mrs. Smith was a dreadfully nervous woman; moreover, she had a young baby, and would naturally find it very difficult to leave home in the morning. Besides, it would mean half an hour’s delay in getting to Pentland Broads, and that would be serious.

Pucker was not the easiest of horses to ride, for the creature gambolled along with a difficult sideway motion which always made Bertha feel as if she were pitching off. But the cross-saddle fashion in which she was riding made her feel safer; she had so much better chance of sticking on than when she sat upon a side-saddle.

She had no whip, but when the first mile or so had been got over at a horrible shaking trot, she managed to cuff her steed into a lumbering gallop, and then she got forward at a great pace. She had no chance of guiding the horse, every faculty being absorbed in the effort to hold on. But Pucker was more used to going to Pentland Broads than anywhere else, and having once had his nose set in that direction, there was not much danger of his going any other road.

“Oh dear, oh dear! I do really believe that I shall be shaken to bits if this sort of thing keeps on much longer!” she muttered to herself, as the sun grew hotter and hotter, and the shaking, racking experience of Pucker’s very best foot foremost made her ache in every limb. Then a long way ahead she saw the houses at Pentland Broads standing out clear against the sunshine, and knew that the long, dreadful ride was nearly at an end.

She could not think what would happen if the doctor should chance to be out. But it was so early in the day, that such a thing would not be very likely, unless indeed he had been away all night.

Cloppety, cloppety, clop! Cloppety, cloppety, clop! Poor old Pucker was entering into the spirit of things with praiseworthy energy; but the worst of it was that the poor old creature had its limitations, and could not understand that its rider would want to go anywhere but to the post office. So it tore past the doctor’s house just as if it were doing the most colt-like bolt imaginable, then it came to a sudden stop before the post office, and stood there as if it were planted, while Bertha sat still on its back, and dared not try to turn the creature round through fear lest it should start off again, like John Gilpin’s horse of immortal fame, and take her straight home again with her errand unaccomplished.

She knew that she could not get off unassisted either, unless indeed she rolled off; but in that case she might sustain some sort of damage, and that risk must not be run, in view of the urgent need there was for her most active assistance now in that stricken household at Duck Flats.

Presently a woman poked her head out from the door of the post office to see why the old horse with the girl on its back had halted so long just outside.

“There ain’t no letters from yesterday’s mail for you, Miss Doyne, and to-day’s mail isn’t in yet,” she said.

“I have not come for letters; I have ridden in for the doctor, but my horse brought me past his house, and I dare not turn the creature round for fear that it will carry me back home without stopping at the doctor’s house. I am not used to riding, you see, and I am not very good at managing horses either. Could you help me get down? Then I will hitch my horse up here and go back for the doctor,” said Bertha, hoping that the woman would not laugh at her for being so helpless.
