And the good Doctor, lifting his eyes from his microscope, looked out upon it all with a quiet satisfaction, and though his lips did not move, his eyes seemed to be thanking God for it all; and thanking Him, too, perhaps, that he was still permitted to gaze upon that fair world outside.  For as he gazed, he started, as if with sudden pain, and passed his hand across his eyes, with something like a sigh, and then looked at the microscope no more, but sat, seemingly absorbed in thought, while upon his delicate toil-worn features, and high, bland, unwrinkled forehead, and the few soft grey locks which not time—­for he was scarcely fifty-five—­but long labour of brain, had spared to him, there lay a hopeful calm, as of a man who had nigh done his work, and felt that he had not altogether done it ill;—­an autumnal calm, resigned, yet full of cheerfulness, which harmonised fitly with the quiet beauty of the decaying landscape before him.

“I say, daddy, you must drop that microscope, and put on your shade.  You are ruining those dear old eyes of yours again, in spite of what Alexander told you.”

The Doctor took up the green shade which lay beside him, and replaced it with a sigh and a smile.

“I must use the old things now and then, till you can take my place at the microscope, Tom; or till we have, as we ought to have, a first-rate analytical chemist settled in every county-town, and paid, in part at least, out of the county rates.”

The “Tom” who had spoken was one of two youths of eighteen, who stood in opposite corners of the bay-window, gazing out upon the landscape, but evidently with thoughts as different as were their complexions.

Tom was of that bull-terrier type so common in England; sturdy, and yet not coarse; middle-sized, deep-chested, broad-shouldered; with small, well-knit hands and feet, large jaw, bright grey eyes, crisp brown hair, a heavy projecting brow; his face full of shrewdness and good-nature, and of humour withal, which might be at whiles a little saucy and sarcastic, to judge from the glances which he sent forth from the corners of his wicked eyes at his companion on the other side of the window.  He was evidently prepared for a day’s shooting, in velveteen jacket and leather gaiters, and stood feeling about in his pockets to see whether he had forgotten any of his tackle, and muttering to himself amid his whistling,—­“Capital day.  How the birds will lie.  Where on earth is old Mark?  Why must he wait to smoke his cigar after breakfast?  Couldn’t he have had it in the trap, the blessed old chimney that he is?”
