FOREST REGENERATION" AND TREATMENT. 65 



Strip Method is a term that is applied to the system 

 where the trees are removed in narrow strips, across which 

 the remaining older trees can easily scatter their seed 

 The best width of strips will depend on the species and 

 the local conditions. Some who advocate this method 

 claim that the strips should not be wider than the height 

 of the trees, while others would allow strips three or four 

 times the height in the case of the Elm, Maples, and Pine, 

 and in the case of Birch even eight times may not be too 

 much. Such strips should generally begin on the side 

 opposite from the prevailing winds at seeding time, so 

 the seed will be blown onto the denuded land. In the 

 case of hillsides the strips should begin on the lower 

 slopes, and the work be continued towards the summit so 

 as to assist the distribution of seed. 



The Group Method is a system of cutting strips suc- 

 cessively on the inside of certain groups. This may be 

 termed a natural method, and for general use, especially 

 in mixed woods and where the land and conditions are 

 quite variable, it is much the best. It gives a chance 

 to adapt the method of cutting to the different species 

 and to the different conditions which may be found in 

 the forest. For instance, a tamarack sw r amp ; dry knoll 

 covered with oak, a steep hillside, and level, rich, rocky 

 land, each covered with the trees peculiar to it, would 

 very likely all be included in almost any forest tract of 

 any considerable size in the Northern States, and each 

 portion should receive special treatment. We can begin 

 with one group or several, and we can start our re- 

 generation in each group perhaps where there is 

 already a good growth of young tree?. In fact this 

 system gives us a chance to begin regeneration where 

 the greatest necessity or the best chance for it already 

 exists.
