When the days grew a little finer, and it was possible to venture out of doors without being almost drowned, Miss Chadwick began to put the "Principles of Agriculture" into practical application. All through the winter she and her assistants—Miss Carr and Miss Ormrod—had worked in all weathers looking after the poultry, the pony, and the new greenhouse, but it was only at rare intervals that it had been possible for the school to turn out and do digging in the garden. The "Land Classes" had, however, been studying the scientific side of the matter. They had analysed soils, estimated the rainfall, and examined the germination of seeds; they understood such mysterious terms as bacteria, protozoa, cotyledons, trenching and ridging, cross-fertilization and spermatozoids, and had some elementary acquaintance with the theory of the rotation of crops. They felt like full-fledged farmers when Miss Chadwick wrote on the black-board such questions as:—
"How far apart should different kinds of orchard trees be planted to ensure enough sunlight?"
"Explain a method of testing seeds."
"What effect has transplanting on a seedling?"
"Describe the difference in structure between a corn-stem and a rose-stem. Make a cross-section drawing of each."
They tried experiments, such as planting in a box six beans with the scarred ends down, and six with the scarred ends up, and noted the results from day to day; they placed blotting-paper between two panes of glass, with seeds next to the glass, put the apparatus in water, and demonstrated the growth of roots; they started one plant in the dark, and another in a light place, grew identical peas in moist cotton or saw-dust, broke the seed leaves from specimen beans to observe what happened, and compared the results of distilled water and tap water as nourishment.
Everybody agreed, however, that it was much more interesting to put on their land costumes and work out-of-doors. Miss Chadwick, whose methods were on the newest lines, taught rhythmic digging, which is far less fatiguing than anyhow exertions, and was very particular about the position of the body and the action of the spade. Miss Todd, looking on with huge satisfaction, felt that she was cultivating girls as well as vegetables, and that her educational experiment promised elements of success. Certain special pupils were allowed to help to attend to the poultry—a coveted honour as soon as the fluffy chickens and ducklings began to be hatched; others were being trained to understand bee-keeping; it was rumoured in the school that Miss Todd's ambition even soared so high as buying a cow.
"Where would she keep it, though?" asked Tattie, who was practical.
"I don't know, unless on the lawn," ventured Jess.
