the other place a good result was obtained, because these acorns 

 were made to germinate before sowing, by placing them a couple 

 of weeks in a warm stable. 



Seedlings of acorns, which have not germinated before sowing, 

 develop a strong tap-root, as is shown in Fig. 1, whilst seedlings 

 from acorns, which have sprouted strongly and whose rootlets 

 are dried up before sowing, form numerous fibrous roots, see Figs. 

 II & III; the upper black roots are the dried up dead rootlets. 



The Figures IV & V show small Norwegian acorns of Quercus 

 sessiliflora, which during transit in autumn to Danmark became 

 heated in the sack and germinated very strongly, but nevertheless 

 after sowing in the spring grew very well and, instead of the sprouts 

 that had dried up in the winter, developed new roots.
