But with all this care, complaints are often made that the seed was not good, - seed that I knew was good, because it had been proved' so, under my own inspection, by an infallible test.

There are various causes of the failure of good seed. One of these is, the injudicious manner in which an attempt is made to start it in a hot-bed. In consequence of the seeds having been sown upon the beds in a rank heat, they are prematurely forced up and easily destroyed, by being pent up without air as soon as the plants begin to appear above ground.

I once planted half an acre of Carrots, rather late in the season. I examined the field one morning, and observed the carrots were breaking through the ground finely. The day had been a very warm one, with a scorching sun, and the ground rather dry; at night I examined the field again, and to my surprise could not, at first sight, see any vestige of the young plants I had noticed in the morning, but upon a close inspection, found them all withered and brown, burnt by the sun. In this way the plants are often destroyed before any notice has been taken of them. Young flower-plants are often destroyed in the same way as were the carrots. Many young plants are destroyed by a minute black fly, or some other small insect, just as they emerge from the ground.

Small seeds are often planted so deep that they cannot push through the soil, while some large seeds are not planted deep enough. A friend has suggested the importance of giving some directions in this work, relative to the subject of planting seeds as to their depth, time of planting, and the time required for the plants to appear above ground. In answer to these inquiries, it may be stated, that in regard to the depth of planting, something depends upon the soil. In light soils, the seeds should he planted deeper than in heavy ones; hut the following directions may he a guide in soils of a medium texture, viz.: Sweet Peas, Lupins, Morning Glories, Four-o'clock, and other large seeds, should.he planted about one inch deep. Balsams, Asters, Centaureas, etc., about one-half an inch. Cockscombs, Amaranth, and many other seeds of like size, one-quarter of an inch. Many of the very small seeds should be sown on the surface with a little fine earth sifted over them, just so as to cover the seeds, and then gently pressed with a piece of board. Great care must he taken with these minute seeds, to keep the surface of the ground moist if the weather is dry, and watch carefully for the first appearance of the plants, when they should be shaded in the middle of the day by spruce boughs, or a gauze covering, such as is used to keep off the insects from cucumber vines. They should be thus cared for until the plants have acquired strength to resist the scorching rays of the sun.

Cypress Vine, Indian-shot, and many other hard-shelled seeds, require a long time to vegetate in the open ground, unless first prepared by pouring scalding water over them, in which they should remain until the water is cold. When planted, thus prepared, the last of May, these seeds will appear above ground in about one week, if the weather is warm.

The Three-thorned Acacia seed will sometimes remain in the ground a year before it vegetates, and I have known Asparagus seed sown late in May, remain in the ground until August, before the plants appeared; but if treated the same as recommended for the Cypress Vine, they will vegetate in a week or ten days.

Globe-Amaranth seeds, {Gomphrena globosa) and some other seeds enclosed in a cottony substance over a shell, will not readily vegetate unless this outer covering is taken off, which may be done with a sharp pointed pen-knife; but this is a tedious process when many seeds are to be planted. I find no difficulty without removing this coating or without scalding the seeds mentioned, if pots of the seeds are plunged in a hot-bed, where there is a powerful heat; they will start in a week or less, according to the degree of heat, but great caution must be observed as soon as the plants appear, to see that they have plenty of air, or they will surely be destroyed.

It is impossible to give directions for planting seeds, that will be applicable to all soils, situations, or seasons; but judgment, discretion and care must be exercised under all circumstances to ensure success. Plants, long propagated by cuttings, lose their power to produce seeds. This is the case with many fine perennial plants, with double or single flowers, that have been propagated by divisions of the roots, as well as by cuttings.

It is a great disappointment and vexation, to find, after you have made ample preparations, and planted your seed, that it was worthless, your labor all lost, and probably too late in the season to make trial of other seed. Perhaps the following hints may remind one of the importance of beginning right.

"To raise your flowers, various arts combine, Study these well, and fancy's night decline; If yon would have a vivid, vigorous breed, Of every kind, examine well the seed; Learn to what elements your plan's belong, What is their constitution, weak or strong; Be their physician, careful of their lives, And see that every species daily thrives; These love much air these on much earth rely. These, without Constant warmth, decay and die; Supply the wants of each, and they will pay For all your care through each succeeding day."
