It is an old and a very true remark, that the various insects tliat afflict the Gardener and the Fruit-grower are jear by year becoming more nu- merous and more destructive. One principal rea- son for this result is sufficiently obvious. The con- tinual tendency ol'modern improvement is to con- centrate vegetable gardens and fruit farms in certain peculiarly fiivorable localities, instead of scattering them evenly and uniformly over the whole country. Hence every injurious insect that troubles the Gardener and the Fruit-grower has an abundant supply of such vegetation, as forms a suitable nidus for its future offspring, close at hand, instead of having to search for it with much labor over an extensive surface of country. Such insects are therefore enabled by this means to increase and multiply with greater case and greater rapidity. Upon precisely the same i)rinciple, if you scatter over the surface of a whole county the amount of shelled corn that is just sufficient to feed a certain gang of hogs, and compel them to seek it out and pick it up every day of the year, they will not thrive so well nor multiply so fast, as if you feed out the very same amount of corn to them in a ten- acre lot, day after day for a whole year.
