Then the next step was to test the invention practically. I put up here in Belfast an experimental factory; I extracted 120 gallons of juice out of each ton of tubers, containing the whole flesh-forming matters of the plant; rasped up the compressed solid matters; separated rather more starch than is obtained by the usual processes, and I had then remaining that which is now lost—to wit, the 120 gallons of juice, and the pulp or raspings, which always contain a considerable quantity of starch, and which forms little mountains at all the potato starch manufactories. These two lost products, the juice and pulp, I mixed together, adding the necessary quantity of stilt, and used as cattle food; and I found, as was to be expected, that it formed a food which they preferred to almost any other which could be given to them.
