close proximity to each other, and at otlier places entirely 

 and distantly separated. Fun^oidsl>ein,Li,- spread over tlu; 

 most oi the ground where the former crop liad been 

 cleared for a length of time, while in several places only 

 newly clciircd as well. They attacked the roots of the 

 young ])lanLs, and, ascending upwards, by tlie time the 

 plants showed signs of lost vitality, reached a few inclies 

 above the surface of the grounil, though in many cases, 

 after pulling up a dead plant and carefully examining it 

 by aid of the microscope, it c(juld not be seen mucli 

 above tlie common axis of the plant. 



Q. 11. Then liow do you account for its attacks — not only on 

 the remotely but also on the newly cleared ground? — 

 A. In the former case, according to the law of natural 

 decomposition, the old stocks were often completely 

 overrun by fungcjids, while stocks left at certain (hites 

 by thinning of the plantation were also attacked ; con- 

 sequently such injurious effects upon young plants are 

 easily accounted for. 



Q. 12. But you chd not state you found this over the whole 

 of your young plantation ? — A. I only found it on certain 

 spots, which 1 attribute to the nature of the soil ; but 1 

 firmly believe it must either have gone, is ncnv going, or 

 will idtimately go, over the whole of the ground where the 

 plantation has been formed. 



Q. lo. Tliese facts, if indisputable, clearly prove then the 

 difficulty of rearing a second crop of tlie same class on 

 ground fcn-merly cropped with timl)er. — A. These facts 

 are indisputable ; and unless plants which are either 

 impervious to the attacks of such fungoids, or capable of 

 surviving them, are introduced, the replanter will be 

 caused grief. 



Q. 14. But you nmst have seen natural reproduction of the 

 same kind of plants in the plantations under your charge, 

 and, if natural reproductions are produced, analogous 

 reasoning would lead me to the conclusion that replant- 

 ing can profitably be done as well, and the more especially 

 that various authors have recorded the fact of replanting 

 succeeding admirably, even when the same kinds were 

 introduced, and grow to profitable dimensions. — A. No 

 t'xpcrionced arborists can deny the fact of natural repro- 

 duction, and I have frecpiently seen it in the case of the 

 Scotch, larch, and silver firs, though not so often in tliat of 

 the spruce or the larch ; but in the case of each, the re- 

 production is never extensive for a considerable time after 

 the former crop has been cleared, though a few natural 

 plants may be seen occasionally in certain parts where
