. c. A wagon driven about the field from one haycock to another, and having a crane which assists in raising the whole bunch at one large forkful. In the example, a longitudinally sliding bar under the tongue is connected by a rope to a roller beneath the bed; from this roller a rope passes over a crane to the loading-fork. The draft on the rope applies the rubbers to the wheels. Hay-rack. d. A crane on wheels or a sled. A mast or tripod on a sled. Hay—mak′ing Fur′nace. Mr. Mechi writes to the London times that he shall hereafter arrange to make his hay by furnace-heat. The apparatus consists of a coke-furnace, and a fan by which the heat is driven through a small chamber filled with grass. In fifteen minutes the grass is converted into hay, sweeter and greener than can be made by sun-drying. The apparatus works in all weathers, and dries grain, corn, and roots as well. Horse hay-rake.

h sword-shaped spikes secured by threaded tangs and nuts. The front edges of the spikes are rounded and smooth, to prevent breaking of the grain: the spikes of the concave have smooth edges presented toward the coming grain for a similar reason. The English still adhere to the flat beaters, like narrow wings or slats, placed longitudinally, and with edges projecting outwardly from the drum. The Americans adhere to the spiked cylinder. A fair trial between the two was had on the farm of Mr. Mechi, Tiptree Hall, Kelvedon, England, in 1853. The American machine was operated by the two persons who had shipped it from the United States: one of them was the present writer. The trial was conclusive. The American machine was driven by a portable engine of six horse-power, and averaged 64 bushels of wheat per hour; 448 bushels of barley were thrashed in six hours. nearly treble the work of the English competing machines, and the grain in much cleaner condition.
