growth. A typical plantation is that of Mr. W. B. Updegrove, 4 

 miles east of Byron. In the spring of 1900 Mr. Updegrove set 8 

 acres to locally grown seedlings, averaging 2 feet high. The rows 

 were 6 feet apart and the trees 4 to 5 feet apart in the rows. The 

 ground had been plowed the fall before. The plantation w r as given 

 two cultivations the first season, one plowing in 1901, no care at all 

 the next year and one cultivation in the spring of 1903. When the ex- 

 amination was made, in June, 1903, the shade was found to be so dense 

 that grass and weeds were unable to get a foothold. The tops met 

 overhead in a thick canopy, the lower lateral branches w r ere dying, 

 and a good form was being developed. The trees averaged 18 feet 

 high and 2 inches in diameter at breastheight, with almost a perfect 

 stand. Three years more of growth at the same rate will result in 

 an average of at least one good post and one stake for every tree in 

 the plantation, and at current prices it will be difficult to find an- 

 other agricultural crop approaching this in profit, when the slight 

 expense for care is considered.
