bus), scarlet runner {Phaseolus), broad bean (Vicia faba), hemp, 

 white mustard. These should be obtained fresh each year, as they 

 deteriorate more or less with age. Those which cannot be had 

 everywhere (such, perhaps, as lupine, castor bean, scarlet 

 runner, and broad bean) may be purchased of seedsmen in large 

 cities. See advertisements in magazines. 



Potted plants. — Such as are grown in window gardens or all 

 greenhouses will suffice. A commercial greenhouse, if accessi- 

 ble, will raise tomato, castor-bean, bean, and sunflower plants as 

 ordered, and will furnish active young plants at any season re- 

 quired, in case pupils cannot grow them either at school or home. 



Malt. — Can be obtained ground or unground at any brewery, 

 or may be made by sprouting barley until the seedlings appear 

 and then drying at about 100° C.
