"Haymaker," he replied shortly.
The answer did not enlighten us.
"'Haymaker'?" repeated Halstead wonderingly.
"Yes, haymaker," said Addison. "So bear a hand here. We've got to hurry, too, if we are to make any hay this year." He then told us that the old Squire had driven to the village six miles away, to get a load of hothouse glass. While we stood pondering that bit of puzzling information, a third hired man drove into the yard on a heavy wagon drawn by a span of work horses. On the wagon was the old fire box and the boiler of a stationary steam engine that we had had for some time in the shook shop a mile down the road.
We learned at supper that Addison and the old Squire, having little to do that day except watch the weather, had put their heads together and hatched a plan to make hay from freshly mown grass without the aid of the sun. I have always understood that the plan originated in something that Addison had read, or in some picture that he had seen in one of the magazines in the garret. But the old Squire, who had a spice of Yankee inventiveness in him, had improved on Addison's first notion by suggesting a glass roof, set aslant to a south exposure, so as to utilize the rays of the sun when it did shine.
The haymaker was simply a long shed built against the south side of the barn. The front and the ends were boarded up to a height of eight feet from the ground. At that height strong cedar cross poles were laid, six inches apart, so as to form a kind of rack, on which the freshly mown grass could be pitched from a cart.
The glass roof was put on as soon as the glass arrived; it slanted at an angle of perhaps forty degrees from the front of the shed up to the eaves of the barn. The rafters, which were twenty-six feet in length, were hemlock scantlings eight inches wide and two inches thick, set edgewise; the panes of glass, which were eighteen inches wide by twenty-four inches long, were laid in rows upon the rafters like shingles. The space between the rack of poles and the glass roof was of course pervious to the sun rays and often became very warm. Three scuttles, four feet square, set low in the glass roof and guarded by a framework, enabled us to pitch the grass from the cart directly into the loft; and I may add here that the dried hay could be pitched into the haymow through apertures in the side of the barn.
That season the sun scarcely shone at all. The old fire box and boiler were needed most of the time. We installed the antiquated apparatus under the open floor virtually in the middle of the long space beneath, where it served as a hot-air furnace. The tall smoke pipe rose to a considerable height above the roof of the barn; and to guard against fire we carefully protected with sheet iron everything round it and round the fire box. As the boiler was already worn out and unsafe for steam, we put no water into it and made no effort to prevent the tubes from shrinking. For fuel we used slabs from the sawmill. The fire box and boiler gave forth a great deal of heat, which rose through the layer of grass on the poles.
The entire length of the loft was seventy-four feet, and the width was nineteen feet. We threw the grass in at the scuttles and spread it round in a layer about eighteen inches thick. As thus charged, the loft would hold about as much hay as grew on an acre. From four to seven hours were needed to make the grass into hay, but the time varied according as the grass was dry or green and damp when mown. Once in the haymaker it dried so fast that you could often see a cloud of steam rising from the scuttles in the glass roof, which had to be left partly open to make a draft from below.
Of course, we used artificial heat only in wet or cloudy weather. When the sun came out brightly we depended on solar heat. Perhaps half a day served to make a "charge" of grass into hay, if we turned it and shook it well in the loft. Passing the grass through the haymaker required no more work than making hay in the field in good weather.
