EVEN AGED MIXED WOODS. 1^55 



a. Sowiiu/ and PlanUnfi in Clear Gutting^. 



Sowing can be done by mixing the seed of two or more 

 species, or by sowing one over the other, either direct or 

 crosswise. The second method must be followed whenever 

 the seeds require a different covering, that which requires 

 the deeper one being sown first. Another method is to sow in 

 alternate strips. Sach sowings are rarely made nowadays, 

 but recourse is had to planting, as it permits the .mixture 

 being arranged in any way which may be desired. The 

 species may alternate by single plants, or by lines, or 

 strip- or group-wise. Again the proportion of one species 

 to another can be absolutely fixed. Planting in groups is 

 specially indicated where the conditions of the soil change 

 from place to place, as each patch can receive the most suit- 

 able species. The size of such groups depends on circum- 

 stances ; if it exceeds a certain limit, the wood can no longer 

 be considered mixed — it becomes a series of pure woods. 



Where a light demanding species is to be mixed with a 

 shade bearer, the former can be given a start of a few years, 

 instead of arranging the mixture by groups. In such cases 

 the mixture is frequently arranged by lines, the light demand- 

 ing (and generally hardy) species being planted first in alternate 

 lines, and the shade bearing species (generally tender in early 

 youth) afterwards in the intermediate lines. 



Another way of giving one species a start over another is to 

 put in plants of different ages. 



In some cases one species is raised with field crops, while 

 the other is planted in, when the cultivation of the field crops 

 has ceased. 



Formerly it sometimes happened that one species was raised 

 by sowing and the other by planting, but this is rarely done 

 nowadays.

 This method is followed in the case of species which are 

 tender during youtli, especiall}' in respect of frost.
