serve as a breeding-place to thousands of noxious 

 insects and fungi, and will be a constant source of 

 danger from fire. 



(b) The strip method is a modification of the 

 preceding method, just as the method of cleared lines 

 is a modification of the method of clearings. The 

 regeneration fellings are carried on successively over 

 long strips cut through the area to be gradually re- 

 generated. The strips are, in fact, long and narrow 

 compartments, in each of which the necessary regenera- 

 tion fellings are carried out in their turn. Thus when 

 the preparatory-fellings, if any, have been started in 

 one strip and the seed-fellings are begun, preparatory- 

 fellings are started in the adjoining strip. When these 

 are successfully effected, after-fellings will be started in 

 the first strip, seed-fellings in the second, while prepara- 

 tory-fellings are begun in a third strip adjoining the 

 second, and so on. Sometimes preparatory-fellings are 

 made several strips ahead in order to hasten regeneration, 

 which might otherwise be somewhat slow in being 

 obtained. 



There is no limit to the length of the strips, but if 

 a sufficient area cannot be covered by them they may 

 be started at two or more points in the forest, care 

 being taken to leave a sufficiency of untouched forest 

 between the different sets of strips. 



The width of the strips is usually not much greater 

 than the height of the trees, but it may vary according 

 to species to be regenerated and to locality. Shade- 

 enduring species, and those which require side shelter 

 more urgently when young, will require narrower strips 

 than shade-avoiding species, especially those whose 

 seed is light and winged and can be carried a consider- 

 able distance. 



As this method is chiefly employed in windy 

 localities the strips are cut as nearly as possible at right 

 angles to the prevailing winds, and they should be 

 started at the leeward end of the forest, unless the 

 condition of the forest require that they should be
