Object. A Study of Commercial Timothy Seed. 

 Materials. Samples of commercial timothy seed. 



Method. Weigh out two and one-half grams of timothy 

 seed. Separate the pure timothy from the inert matter, and 

 the impure seeds and weed seeds. Place 100 timothy -seeds in 

 a germinator, and leave for about 14 days, examining them at 

 intervals of 24 hours, until they commence to germinate. 

 Tabulate the data in the notebooks for this, as you did for 

 similar work on the legume seeds.
