At another signal the splendidly drilled young fellows scampered off, carrying not only their tools, but their benches, tables, stools, and even debris along with them, and, disappearing in less than a couple of minutes, left not a chip or shaving behind. It would take a good many pages of close writing to give anything like a detailed account of all that I saw. I must pass over much in order to emphasise one or two very telling incidents. The Doctor presented a sample of all his wares. One of these was a very touching sample-- namely, a band of cripples, who made their way slowly on crutches down the passage to the platform--for it is one of the noteworthy points in this Mission that no destitute boy is turned away, whether he be well or ill, crippled or sound. So, also, there was a small procession of neat, pleasant-looking nurses, each leading one or more mites of forsaken humanity from "Babies' Castle." But it seemed to me that the kernel of the nut had been reached, and the foundation of the God-like Mission laid bare for our inspection, when the raw material was led forth. We had got accustomed by that time to turn an expectant gaze at a far distant door when the Doctor's voice ceased or his whistle sounded. Presently a solitary nurse with the neat familiar white cap and apron appeared at the door leading two little creatures by the hand. A hush--a distinct though indescribable sensation--as of profound pity and pathos,--passed over the vast assembly as a little boy and girl direct from the slums were led forward. The nurse had to walk slowly to accommodate her pace to theirs. Half naked, ragged, dirty, unkempt, bereft of their natural guardians, or forsaken by them--helpless, yet left to help themselves almost before they could walk! Forward they came to the central platform, casting timid, wondering glances around at the mighty host of well-to-do beings, not one of whom, perhaps, ever knew what it is to hunger for a whole day and lie down at night with a door-step for a pillow. Oh, it was pitiful! the Doctor advanced to these forlorn ones and took them by the hands with inexpressible tenderness, and then, facing the assembly, broke the silence and presented the human material which it was, under God, his mission in life to rescue. Then turning abruptly to the flower-bed in the orchestra, he signalled with his finger. A flower that might well have been styled a rosebud--a neat little girl in pink with a natty straw hat--tripped lightly down and stood on the platform beside the poor waifs. Looking up once more to the entranced audience and pointing to the children, the Doctor said-- "Such as these are, she was but a few months ago, and such as she is now they will soon become, with God's blessing." I may not quote the words correctly, but that is my recollection of the substance.
