this I will not now take tirae anv more,but I could have accompli shed 

 it well in the course of 2 years,if I had worked on it fron time to 

 time. My metereological studies have taken me a c/eadful time, so that 

 everything eise remained undone.. I have put together the rain for all 

 years frora 1800 - 1807 for all observations in Germany acco^ding toc 

 dif f erences, just as Dove did. for the temperatures of this timespan,, 

 in order to prove.that the change in weather fron month to month and 

 year to year {tE&xxM&fcxcteja&Md: with less or raore rain does not depend" on' 

 local causes. I will publish the rain diffe^ences right away in the 

 metereoloßrical Journal. For America this special question ma'U&s no sense,, 

 and the^e is no harm, if Americans stick to the superstition, that forest^ 

 could inf luence the climate. But if the government does not seriously 

 think of the preservation of forest land , or if the owners of forest 

 land|do not make up their minds to manage the timber resources-, or think- 

 of errowing. new forests, then lack of wood could occur in specific areas 

 (as I have heard) , though I believe, that no human being will 1 preserve 

 woods on good soili and on poor soil no human will eliminate the woods>, 

 and that prairie will never sustain- rieh woods r . In every case,a reaso- 

 nable management of what is on hand is necessary, and replacement growth 

 desirable. Today mankind does not have the time to wait for the slow 

 process of restoration of the primeval forest. In Europe f the supersti- 

 tion, that the forest was a preventive for dryness- and floods^, has not 

 benefited in any way, in that repmlation of rivers, construetion of re- 

 servoirs, Irrigation canals were not carried out, so that the owners or 

 forests come into tanprer to be only nominal owners. (Thoue-h the letter is 

 clearly written, this sentence raakes no sense to me. E.D..)..Now I anr 



finished with the major job, and will gain time dail!y,to devote seve- 



which I waj3 very unhappy to lay aside 

 ral hours to the pinesjj because there remains something really* good and 



new, but not so in jobs of compilation.. And though I have no prospect
