CANADIAN FORESTRY ASSOCIATION. 53 



Generalizations in forestry are very frequently met, each observer judging the 

 whole continent from the facts existing in the locality with which he is best acquaint- 

 ed. I warn you from jumping at conclusions on the basis of local evidence. 



Mr. STEWART. Perhaps I might be able to reconcile the different views which 

 seem to be held by the speakers regarding this subject. 



I remember at one of our committee meetings we had a discussion over the growth 

 of spruce. Sir Henri Joly de Lotbiniere put an example before us, saying that it took 

 about ten years to grow one inch in diameter. The lieutenant governor of New Bruns- 

 wick cannot be here, unfortunately (as Colonel Loggfe said), but if he were here I think 

 he would be able to tell you that it is possible to produce one inch in one year, and that 

 he has done it on his limits in New Brunswick. I understood at the time that they 

 go over his limits about every ten years. 



He aftejwards sent to my office an exhibit from his limits, showing about threo- 

 quarters of an inch per annum, that is taking the two sides on the measure. The aver- 

 age would be over half an inch, and nearly three-quarters of an inch in diameter. Sir 

 Henri Joly de Lotbiniere has counted from the interior and the growth is slow. Gov- 

 ernor Snowball's was from timber cut where the moisture was very great and where the 

 growth was very fast. 



I just mentioned this to show that perhaps the two views are not altogether irre- 

 concilable. 



Mr. KNECHTEL. I think Dr. Schenck has probably misunderstood my position. I 

 contend only this, that this practice of going into the woods and cutting to a diameter 

 limit periodically, as the lumberman does in Canada and in New York, will not give 

 a permanent supply of conifer timber. Dr. Schenck tells us that he gives artificial 

 conditions for regeneration. That is a different question altogether. I do not know 

 where he found the natural regeneration of spruce so good in Germany, for I was all 

 through the mountains, the Erzgebirge, the Harz, the Thuringian forest, the Vosges, 

 the Odenwald and the Black Forest. I travelled thoroughly over the country and did 

 not pee it. I also had excellent guides the forstmeisters themselves who have charge 

 of these forests and I inquired particularly concerning this point at Sulzburg, where 

 Dr. Carl Phillip is in charge, and there got definite information that the spruce is a 

 failure so far as natural regeneration is concerned not an entire failure, but that it 

 i.- not sufficiently reproductive. I think that explains my view of the matter. 



Dr. CLARK. In regard to this matter of the natural regeneration of the spruce, I 

 think that both the gentlemen who have spoken have stated the facts correctly, that is, 

 in Germany you can find places where the spruce reproduces itself, you can find other 

 places where it is not so satisfactory. 



I wish to say a word in regard to some natural reproduction of white pine which 

 has come under my observation. 



About two years ago I was making an examination of a large tract of pine land 

 in New Hampshire, which had been lumbered over about 00 years ago. The best of the 

 timber only was then taken. The usual after lumbering fire swept through the slash
