heavily) have tried leaving a certain number of special stems 

 beyond the final felling, as in the case of the pine. The result 

 has been very bad, as the stems, suddenly laid bare, became 

 covered with epicormic branches and died off, in spite of pruning. 



One new thing was introduced during the war, namely, the 

 tapping of the Scots pine for resin, which is not generally con- 

 sidered a paying proposition. 



Whortleberries are collected in Haguenau to an extraordinary 

 extent, and quite free, by all and sundry. The value of this 

 was estimated to be 120,000 frs. before the war, during the war 

 880,000 frs., and now 350,000 frs. They go far afield — to 

 Holland, and even to England. Why should not this minor 

 forest product bring in a revenue to the owners of the forest ? 



II. — A correspondent in the Revue des Eaux et Forets, 

 taking for text the strip fellings in Haguenau mentioned 

 above, suggests a scheme for arranging the strips which would 

 allow of regenerating the whole of an area naturally, and 

 thereby avoiding any planting. He supposes, as an example, 

 a rotation of sixty years, and arranges his strips in six groups. 

 The following diagram shows the order of the fellings. It 

 will be seen that there is always a strip of seed-bearing trees 

 alongside a cleared strip. 



The above plan might be of use among ourselves when we 

 have to deal with Scots pine on sandy or gravelly soil, where 

 natural regeneration is easy. But assistance by the removal 

 of heather, etc., in the cleared strips will always be highly 

 advantageous. 



Later on, when the Scots pine crops are older, the underplanting 

 with beech will sometimes, in a sandy soil, as much as double the 

 growth of the Scots pine, according to M. C. Morel, who has
