LETTER FROM ELIS NILSON. 127 



under-planted with spruce have began to die out after ten to 

 fifteen years. An equal mixture of larch and fir (P. silvestris) 

 has no prospect for the future except on condition that the fir be 

 not allowed to put the least pressure from the side on the larch ; 

 but the fir thinnings being of much less value than those of the 

 larch, the unmixed larch-wood is, as I have already mentioned, to 

 be preferred. I have no experience as to whether larch and oak 

 will thrive together, but I think it is very probable they would. 

 The oak has been proved to thrive excellently in Sweden, even 

 as an under-plantation in old fir-woods ; and it might therefore, 

 with still greater profit, be raised under larch-woods of from 

 forty to seventy years of age. Plantations of larch and oak 

 of the same age — in which case, however, the distance between 

 the rows must be at least 8 feet — may have a prospect of good 

 success. 



As to the age at which the larch ought to be planted out from 

 the nursery, I think that plants two years old, once transplanted, 

 have the greatest prospect of being removed without damage. 

 In cases where there is abundant growth of grass, however, older 

 plants ought to be used, and then I should advise plants of three 

 years, twice transplanted, to be taken. 



In conclusion, I wish very warmly to recommend the perusal of 

 the publications of Forstrath Krommelbein in Varel (Oldenburg) 

 regarding the larch (Zeitschrift fur Jagd- und Forstwesen, edition 

 1888); even Dr A. Oieslars : Separatdruck aus dem G entralblatt 

 fur das gesammte Forstivesen, edition 1899, Febr. und Marz — to be 

 ordered from die Buchhandlung W. Frick in Wien I., Graben 27.
