The threshing-machines are numerous, and are of very excellent construction. The improvements that have been made in them are very striking. It is really a curious sight to see the sheaves of wheat placed in at one end, and the winnowed grain passing out ready sorted into bags at the other; while the straw is carried by a mechanical contrivance to carts to be taken away. Here also we see digging machines, to perform wholesale the ancient duty of the plough, which was at all times an imperfect implement. The ploughs, however, that are shown are of the very best description, with many useful improvements. Portable houses for emigrants and others, and an immense assortment of entrance gates, and of poultry, sheep, and cattle fencing are also here to be found. Haymaking machines for scattering the hay, and horse-rakes, are important substitutions for hand-labour. Draining-ploughs, for preparing a pathway for the pipes, and for laying the tiles, and draining levels are also exhibited. A large collection of chaff-cutters, bruising and grinding mills, oilcake breakers, steaming apparatus and pulping machines (the pulping machines are for preparing food, such as turnips or carrots, for cattle), grass-mowing machines, both for hand and horse-power, carts of every description, liquid manure carts, field rollers, and several descriptions of clodcrushers, brick and the machines, mortising and boring machines very well suited for making gates and hurdles, makes up the sum of this interesting exhibition.
