The ploughing, fertilizing and harrowing were done for Peter. The soil was just the sort potatoes thrive on, a sandy loam. After the furrows had been made about six inches deep and two feet apart, Peter put a sprinkling of chemical fertilizer into the bottom of each furrow. This was sprinkled on as one puts salt on potato before eating it. Over this he placed some dirt so the fertilizer would not burn the potato.
Early the morning of planting Peter cut his seed potatoes. The date was the 1st of April, not a bit too soon to get in early potatoes.
The seed potatoes chosen were fair, smooth specimens of good size. These he cut so that only one eye was left to a piece of potato the size of a hen's egg. These pieces were dropped into the furrows at distances of fifteen inches apart and four inches deep. After covering, the man went over the potato patch with a harrow. A boy might use a rake for this work, but as Peter's patch was a small part of his grandfather's field the harrowing of the whole was done by the man.
When the little potato plants were well up Peter sprayed them with Paris green. This was wise because he thus got ahead of the potato bug. Some one may like to know how to mix up Paris green. The proportion used was one tablespoonful to a pail of water. This was put on with a watering pot every two weeks, thus Peter kept his potatoes quite free from bugs.
Although the rest of the potato patch was cultivated by the horse, Peter used the hoe. He could not plough, for Peter was a rather small boy for his age and not very muscular. The secret of potato culture is to cultivate well and keep the bugs down.
He dug his potatoes about the middle of June. From the one quarter acre his grandfather had lent him for his garden Peter dug seven bushels of potatoes. At the time new potatoes were selling for $1.25 per bushel. His father bought three bushels and the other four were sold in the city to Philip's mother and friends.
The constant working of the soil for potato culture gets it into a fine mellow condition exactly right for celery. Peter's grandfather suggested that the boy put this in, and so have another crop, a fall one.
Although this soil had been well fertilized in the spring for the potatoes this was yet not sufficient for celery culture. Celery ought to be started either indoors in flats, or in a hothouse or seed bed late in February—transplanted to other flats, and again finally to the open ground.
To prepare for the celery trenches were dug three feet apart and one foot wide. The earth thrown out in trench digging was piled between the ditches to be used later in banking up the celery. These trenches were six inches deep. In the bottom of the trench was put some enriched manure. This was of different materials. Peter used well-rotted barnyard dressing, a little hen manure, and about the same quantity of chemical fertilizer. Hen manure is rich, so he did not use the bulk of that. Over this was put an inch of soil.
Celery plants should be set about six inches apart in the trench. First cut them back; that is, cut off about one quarter of the root and one-third of the top. This cutting back increases the spread of root-growth later and decreases the amount of respiration of water from the leaves. The top alone grows more stocky and bulky.
