Forest Club Annual 



The \y 2 year seedlings are not desirable planting stock 

 because of insufficient root development. The y 2 1 1 trans- 

 plants are not suitable because the cost of raising them is ex- 

 cessive and the l / 2 year seedlings are too small to handle in 

 transplanting. The \y 2 1 transplants are undoubtedly the 

 best, because of their excellent root systems and the comparative 

 ease in handling them both in transplanting and in field plant- 

 ing. The y 2 1 transplants have an insufficient root system 

 and the y 2 year old seedlings are very hard to handle in trans- 

 planting because of their small size. The y 2 2 transplants 

 are not desirable stock as these are too large to handle satis- 

 factorily in field planting and also their small size as seedlings 

 make them hard to transplant. One thing of interest is the 

 high per cent of living plants for each class, when in fact the 

 per cent of moisture in the soil was very low. 



The three characteristic soil types in the Western Yellow 

 Pine type are the malpais, limestone and cinder soils. Select 

 \y 2 1 Western Yellow Pine transplants were planted the latter 

 part of April, 1912 ; counts made in August showed the follow- 

 ing results : 



Although results show that planting is feasible on all the 

 soil types, excessive cost of planting on the rocky ridges pro- 

 hibits it here and furthermore, the natural reproduction is gen- 

 erally sufficient to give fully stocked stands on these areas. 



Below is given conservative costs of planting per acre in 

 two different soil types. The difference in cost of planting on 

 the cinder and limestone soils is so small that only the limestone 

 need be given.
