Most honored Sir ! 



Due to my ef f orts< about the questiorr of forests^ I have beere en- 

 tangledr in such polemics, that , besides the raany^jobs of my professiorr,, 

 there remalns not enough time, to examine your pines properly,of whichh 

 I T have made preparations.. It seeras to me, that several! species of 1 

 Rozli could be never-the-less dif f erent f , , but that needs- a entirely se- 

 rious comparison«. Recently I reeeived a giant cone of a pine und er- the 

 name Coulterl macrocarpa . -I had not considered such huge differences 

 from ponderosa . The needles of all these species have certain siraila- 

 rities^ in strueture, and only australis is strikingly different fromr 

 the closely related- eubensis , in that the rosin duets are iraraediate- 

 ly grouped around the vascular bundles. . Of the two-needle Ainericans I 

 KKK omly resinosa has a strikingly different strueture.., whereas the 

 others, similar to silvestris, halapensi s, , Brutia,, Banksiana, inops,, 

 glabra, , though diverting in the e-oiderrais and numberof rosirr duets,. 

 resemble each other.. nl yv pung ens , wi t h a stronger epidermis than e.g. 

 Pinaster departs with raore rosin duets of similar Organization ( as 

 australis ) For this reason I do not have a special 1 idea about apala- 

 chicola , as she seeras to me to be very similar to mi^Tis (this last 

 word is sertched out, E.D. )• I believe however, that I shall find 

 still many dif f erencesr, once I will have examined the material in 

 longitudinal and cross- cuts. Hopefully, I will get to it next month:.^. 

 I posess until now only cones of 4 Acahuite , Lambertiana , ? Strobus. munl- 

 cata , oocarpoides, radiata, pung ens, , inops , Taeda , , rigid a, . ponderosa, , 

 and the closely related' Benthamiana ( if the cones are properly iden- 

 tifiedK patula , leiophylla , Mont ezumae. . What I reeeived' as oocarpa, 

 was a brutia, and what I" got as insignis was Larisiov Of nut^pines 

 all is mi ssing,also of mitis I have no idea. I am, however , content 

 that through the lack of cones I am f orced to- take a sharper look
