& SEEDS . 
embryo of a seed is really a small plant which has been 
arrested in its growth and is now lying dormant. We 
know from experience that under certain conditions, and 
certain conditions only, this small plant will develop 
into a larger one. What these conditions are, and what 
becomes of the different parts of the embryo, as well as 
the relation between the plant and its environment, we 
shall try to ascertain by experiments that are to follow. 
Each student will perform all experiments person- 
ally, excepting those preceeded by the word class or 
group, which will be performed by students selected by 
the instructor. All students will, however, make ob- 
servations on all class and group experiments and.write 
them un, just as tho they had performed them personally. 
Exp. 1: *In some moist soil plant three or four of 
each of the following seeds: bean, castor-bean, four- 
o’clock, corn, pea, maple, squash, and clover. Cover, the 
seeds with soil, approximately 2 cm. deep, and set them 
in a warm place. Keep the soil moist. Study the de- 
velopment of these seeds for two or three weeks, noting 
what becomes of the different parts of each variety; 
the time it takes each to come up, the development of 
leaves, the position of the leaves, opposite or alternate, 
the kind of leaves, simple or compound, netted or parallel 
veined, the kind of root system, tap or fibrous, etc. The 
roots are to be studied, at the close of the experiment, by 
* In writing notes on the experiments use the following headings and write 
a paragraph under each: 1. Description of Experiment. 2. Results. 3. Discus- 
sion of results. 4. Conclusions. The descriptions of the experiments should be 
brief and concise. It can frequently be best given in connection with a sketch 
of the apparatus used. The results must be recorded in detail. The discussion 
should be clear and logical and the conclusions definitely stated.
