“I understand,” nodded Nelson.

“Label all the squares plainly. Mass everything of its class in distinct heaps. That is the first start in your work.”

Frank had some of his regular village chores to do. He was gone over an hour attending to various duties.

As he came back to the store again, Frank was spurred up by the busy hum of industry. Half-a-dozen urchins peering enviously in at the open front door made way for him. He gave them a kind word and stepped inside to take a sweeping view of his juvenile working force.

A great rattlety-bang was going on as the boys pulled over the heap of debris. Hands and faces were grimed. There were some blistered fingers, but the boys were working like bees in a hive.

The chalked-off sections had begun to grow in number. One was labelled “Needles.” Frank stared in some wonder. There were papers of needles whole, and others with half their original paper coverings burned away, of loose needles, some rusted and blackened, some still bright and shining; there seemed to be thousands upon thousands.

Then there was a lot of pieces of lawn mowers, blades, wheels, screws, cogs and axles. Hinges of all sizes and qualities showed up prominently. Pocket knives, scissors and carpenter tools were likewise greatly in evidence.

One pile was growing rapidly with the minutes. This was a heap of apple corers. It was a contrivance with a small wooden knob. A screw held a tapering piece of thin metal, which penetrated the centre of an apple. Then a twist was supposed to cut out the core.

From letters in the zinc box which Frank had read, he knew that purchasers of this device had complained about it greatly. In the first place it was arbitrarily set for one uniform cut. No matter whether the apple to be operated on was large or small, the hole made was exactly the same. If the fruit was hard and crisp, according to the letters of complaint the corer split the apple. If it was soft, the corer mushed the apple. There were already sorted out several hundreds of these corers. Frank wished he could get hold of them and improve them.

Frank looked over all the selected stuff in view. Then he went in turn to the village blacksmith, the local hardware store and to a druggist friend. He returned with some sponges, soft rags, sandpaper and a can of oil. He chalked off new spaces at the rear end of the store, three being devoted to each article labelled. Then he ordered his helpers to grade the various utensils dug out of the debris. Thus, hammers: those burned beyond practical use were put in heap one, second best, heap two; those that were only slightly marred were placed in heap three.
