trees, according to G. M. Bentley, of Knoxville, Tennessee. 

 Basswood yields in greater quantity as one approaches the 

 mountain country where temperature conditions of climate, j 

 during its period of bloom, are similar to those of Wisconsin. 

 Tulip poplar also varies in yield according to its elevation and 

 the type of soil in which it is growing. The reasons for this are 

 as yet a mystery and offer a fertile field for investigation. 



In Maryland, for instance, according to G. H. Cale, of College ' 

 Park, there are regions where tulip poplar grows in abundance 

 and where, with identical trees within a few dozen feet of each 

 other, some fail to yield nectar, while others do. It has been 

 noticed that the tulip, growing on an elevation, apparently yields 

 nectar abundantly. Trees growing further down the slope, in 

 exactly similar weather conditions throughout the year, often 

 fail to yield nectar appreciably. It is believed that the type of 

 soil, which is know^n to vary in such cases, has much to do with 

 this variation in value of tulip poplar as a nectar producing plant.
