Fig. 4. White lupins, growing from successive plantings in a germinating case made of two sheets 

 of glass tied together with cotton wadding next to the back glass and a layer of black close-woven 

 cloth between the wadding and the glass in front. The cloth is for a dark background and to force 

 the roots to grow in one plane between the cloth and glass in front. The case is kept standing on 

 edge (see Fig. 5). The seeds are planted on the upper edge between the front glass and the black 

 cloth, and kept moist (with water until rootlets appear and then with the solution). Strips of cotton 

 should be used to cover the edge and protect the seeds from drying until the plants begin to grow 

 (see Fig. 5). At the end of two weeks there is a living chart showing successive stages. 



Fig. 5. Germinating cases, described in connection with FJg 4, arranged in card-catalogue style 

 in an enameled pan. By this arrangement space is economized and the roots in each case, except the 

 one in front, are darkened by the adjoining case. A piece of black cloth may be used to cover the 

 front glass. The excess solution poured over the upper edges is collected in the pan, and from time 

 to time is used again to moisten the cotton above.
