Until within a comparatively short period, but little attention has been paid to the production of machines for harvesting the various crops.
During the past few years, however, many valuable inventions have appeared. Among these we notice Ketchum's mower, Hussey's mower and reaper, and Wagener's grain and grass seed harvester. The latter machine gathers only the grain and seeds of the crop, leaving the straw to be plowed under the soil, thus maintaining its supply of soluble silicates, and increasing its amount of organic matter. After taking the seed heads from the standing straw and grasses, it thrashes them, blows out the chaff, separates the different kinds of seeds, and discharges them into bags ready for market. It consists of a car containing the machinery; to this may be attached any required number of horses. The inventor affirms that it has harvested the grain of two acres in one hour, performing the work with accuracy.[AP]
There is much truth in the following proverbs:
"A garden that is well kept, is kept easily."
"You must conquer weeds, or weeds will conquer you."
What are the two great rules in mechanical cultivation?
It is almost impossible to give a recapitulation of the matters treated in this section, as it is, itself, but an outline of subjects which might occupy our whole book. The scholar and the farmer should understand every principle which it contains, as well as they understand the multiplication table; and their application will be found, in every instance, to produce the best results.
