METHOD OF VALUING GROWING TIMBER« 



particularly applying to his Majesty's New F'orest in Hamp- 

 shire, was published by T. Nichols, Purveyor of the Navy 

 for Portsmouth Dock-yaid. 



In this paper it is said, that " there are to be seen in 

 many parts of ^he forest from 40 to 50 fine oaks standing 

 on an acre, that will measure ope with another two loads a 

 tree." 

 Si>jTity from '* Several woods in the forest are almost ruined for want 



^eslecting to of thinning, and it's being done at proper times; parlicn- 

 ' Jaily the eijclostire* that were made in the year 1700;-^-^ 



these were oris^^inaHy well planted, and great numbers of 

 trees brought up in them» which now rP»r>ain so close toge*. 

 ther, that th,ey are nearly stagnated, particularly m SaHs- 

 burVi Trench, Bnmley Coppice, and Woodfidiey; and, 

 although it is QQ. ypars since they were planted, the trees 

 will not measure, one with another, above six or seven feet 

 a tree ; whereas, if the business of thinning had been done 

 as it ought, the remaining trees (after drawing ignuch useful 

 timber) would by this time have been of a size nearly fit- 

 for naval uses; as in some of the woeds, that were planted^ 

 at the same time, the trees which have had room to expands^ 

 and a. free air a^dmitted to thciq, will measure from 70 to. 

 80 feet." 



Observations on the Growth cf 1^'nnher. 

 1;iniber j?rn-ws The rings observable in the transverse s-cction of a tvee at 

 S^ n'exuhe'^ '^^ bptrcnd are the same in number as the years oi its age , 

 '^4p, an additional ritig being produced annually, in consequence 



of the annual risio" of the sap. The rings are nearly con- 

 centric in trees that have grown in the interior of close 

 shady wooxls, but eccentric in others, being of different 

 breadths on the northern and soi tb 'rn sides of such as have 

 grown single, or in any other situation, where their boles 

 have been much expo.ed to the rays of the sun. This dif- 

 ference is occa-^ioned by the different degrees of heat, to 

 •which the opposite sides of the boles of trees are exposed. 

 And, indeed, we find these rings are always broadest on 

 that side of the bole or stem most wiirmed by the siin. 

 llence we see the utility of exposing th^ir bol^s as much 



•a'".
