actual practical conditions, and therefore is likely to 

 mislead. 



The following j0.gures, compiled from tests made at the 

 Pennsylvania State College (Rep. Penn. State College, 1886, 162), 

 indicate the differences between mere sprouting and germi- 

 nation. The percentages of germination given in the first 

 column were obtained from sprouting tests, while those in the 

 second column, from the same samples of seeds, were obtained 

 from plantings made in a hotbed. Although these figures appear 

 to lessen the value of sprouting tests, it is nevertheless true 

 that, in general, a high sprouting test indicates a high vegetative 

 power ; but the vegetative " power is often or usually less than 



the sprouting power.
