 eoininiuiieation, uiuler date oC .liiiuiaiy 1 1, 1887: 



All tliivsit trees ^vv^l' foniiil ill an olil ]>;iMt iiii' atljoiuiiiK my land un the iiortli and having; Hiinilar aspect anil Hoil. 

 A l'riii};<" '•' 'all White I'iiie tiiMl)ir snrroiiiuls it on three siiles, north, I'ast, and .south. I'lic ilistatu'e acmsH this <>|Mn 

 lanil fiDiii north to smith is about (iO roils. This lanil has hoin in ])astiire frmri lifty to oiH3 liiiiidieil ye;ii8. It w;is 

 I'orinei ly thickly covind with iiiosH, 8\veot fern, and other lo\v-t;rowin;; linshcs, in the Hhadi^ of whieU auim:il.s finind 

 some grass. Althon;;h thus siirronndud liy t:ill pines their si ids sildoin sprung up. 



Nut luaii.v years helore these trees started a portion of this land \v:im plowed ;ind jilaiitcd w ith ]iotatoes one year, 

 and then turned out to pastime ;i^ain, wliennpon youn;; pines iniinediately sprung iiji. These were (Mit down first, 

 but they eontinued to come up so abundantly that they were allowed to Krow, and now the patch that was planted 

 with potatoes is quite thickly covered, in m:iny places too thickly, with trees like tlio.se measured. This fact shows 

 the importance of tiirning up the soil so that the .seeds that fall upon it may have a chance to take root. Only hero 

 and there a seed will lind lodgment on land that is covered with moss and low-growing bnshes, no matter how 

 abundantly seeds may be sow n upon it. 



IIow sucli tree.s eontiime to jjrow i.s shown In Talile 111. P'roni tlie iiieasiirt'inents it appears 

 tliat a steady growth eontiuues, whieh, by tlu^ Imndredth year has broiiyht the tree to a hei},'ht of 

 near 100 feet.
