is shown by weights and measurements of the stocks given below. 
A calipering of these stocks in 1891 showed no appreciable 
average difference in diameter.

The above data were secured in the following maimner: The 
first week in November each individual stock was dug carefully 
and the dirt cleaned from the roots. It was then calipered 
and weighed. The top was then cut off and weighed separately. 
These data are, perhaps, the first published showing the superior-
