 liank, and those existiiiu' <'" the ivrf, ;ind which are the most nccessilile, re|iresent the 

 clli'cts ol' denudation cMciidini;- over at least iivi' centuries. 



The relative positions ol'all the trees ohsi'rvtd are sei'ii in tlu" plan and sect ion, from 

 ■which it would ap|ear that they occur in i.;roiips. 'I'here is reason to Itelieve. l)owev(>r, 

 that these erect trees are onlv survivors of n mueii more dense forest, of which the 

 ■weaker and more perislialilc trees had lieeii ovi'it hiowii. Tlu' positions uf the trees

The mannt>r of accmnulatlon of the lieds enclosing the I'reet trees is rendiTod evident 

 l»y their eharauti'r and cmiti'iits. and has )ieeii noti(*ed in my 'Acadian (ieolouy,' p. i;k),

The underclay. No. l:l. re|irescni> a loamy soil on which Siijilliirui' must have 

 nourished for a lon^' time, iillinu' it with their roots and lontlets. The result was the 

 accumulation of the cnal, No. 1-2, which is filled with ilattened ami carlionisi'd liark of 

 these trees, as is the hlack shale coiistiiutiiiL;' its roof llark of [j<'i>lihijloiios'' is howevt'i' 

 lai'LTely a.ssociated with that of Sii/iUiiria in these heds. Leaves of < nnlath-.s also 

 occur in this coal, and its mineral charcoal shows under the micro.scope bast lilires of 

 the inner hark of .Siiiillnriu. with scalariforni, uniporous, and reticulated tissues, 

 jiroliahly hehm^Ini;' to the wnod <>{' Sli/i'llari((, l,r/)iilnjl,,i/ns. i'aliiiiiiJ<:i, and Curdnilcx.^' 

 J,eaves of the latter u'einis, as I ha\'e shown {nji. cit.). constitute a lai'j^'e part of some 

 thin coals at the .hij^'nins. and smue portion of the lio'iieous matter, which in former

 shows shreds of epidermal tissue with u k^w rounded hodies, prohahly spores of I'erns 

 or lycopiids.;}'
