Keep a record of the number that have been removed from each square and later figure out the percentage of germination for each kind. A seed that produces a good healthy shoot has strong vitality. Seeds with weak vitality should not be planted. Below is given a model record of a seedgerminating test. (Exercise 60, page 112.) Germination of seed. It is sometimes best to germinate seeds before planting them. Large seeds like yam bean may be soaked in water a few hours, and then kept in a damp cloth to germinate. Lettuce seeds may be FIG. 62. One large germinating table may be used, instead of many small boxes. The plants on this table (Philippine Normal School) get the sunshine till about eleven o'clock in the forenoon. Each pupil plants an area 60 centimeters square and takes care of it. germinated by placing the moistened seed in a bowl and then covering them with a green leaf upon which a quantity of wet sand is placed. Set the bowl in the shade. After two days, or as soon as the seeds have germinated, mix them with moist soil and sow them in a garden plot; rake the seed in with the soil, scatter straw over its surface for a mulch (Fig. 63), and sprinkle the plot with water.
