And yet it was a bustling, prosperous town, with so much money in it that it seemed strange that a man with a trained brain and dexterous fingers should be starved out of it for want of employment. At his desk, Dr. Horace Wilkinson could see the never-ending double current of people which ebbed and flowed in front of his window. It was a busy street, and the air was forever filled with the dull roar of life, the grinding of the wheels, and the patter of countless feet. Men, women, and children, thousands and thousands of them passed in the day, and yet each was hurrying on upon his own business, scarce glancing at the small brass plate, or wasting a thought upon the man who waited in the front room. And yet how many of them would obviously, glaringly have been the better for his professional assistance. Dyspeptic men, anemic women, blotched faces, bilious complexions--they flowed past him, they needing him, he needing them, and yet the remorseless bar of professional etiquette kept them forever apart. What could he do? Could he stand at his own front door, pluck the casual stranger by the sleeve, and whisper in his ear, "Sir, you will forgive me for remarking that you are suffering from a severe attack of acne rosacea, which makes you a peculiarly unpleasant object. Allow me to suggest that a small prescription containing arsenic, which will not cost you more than you often spend upon a single meal, will be very much to your advantage." Such an address would be a degradation to the high and lofty profession of Medicine, and there are no such sticklers for the ethics of that profession as some to whom she has been but a bitter and a grudging mother. Dr. Horace Wilkinson was still looking moodily out of the window, when there came a sharp clang at the bell. Often it had rung, and with every ring his hopes had sprung up, only to dwindle away again, and change to leaden disappointment, as he faced some beggar or touting tradesman. But the doctor's spirit was young and elastic, and again, in spite of all experience, it responded to that exhilarating summons. He sprang to his feet, cast his eyes over the table, thrust out his medical books a little more prominently, and hurried to the door. A groan escaped him as he entered the hall. He could see through the half-glazed upper panels that a gypsy van, hung round with wicker tables and chairs, had halted before his door, and that a couple of the vagrants, with a baby, were waiting outside. He had learned by experience that it was better not even to parley with such people. "I have nothing for you," said he, loosing the latch by an inch. "Go away!" He closed the door, but the bell clanged once more. "Get away! Get away!" he cried impatiently, and walked back into his consulting-room. He had hardly seated himself when the bell went for the third time. In a towering passion he rushed back, flung open the door. "What the----?" "If you please, sir, we need a doctor."
