NOTES AND QUERIES. 5 I 



Science at the Agricultural Institute of Paris, who said: — 

 ^^ Natural regeneration is, from the cultural point of view, the 

 object which foresters must aim at. So far as I am concerned, 

 I believe, according to the lessons of our illustrious masters^ 

 that the forester must help nature, and, as much as possible, 

 make use of her, but without trying to take her place, and I 

 look upon artificial regeneration, whe?i circumstances do not 

 impose it, as a robbery at nature's expense, a robbery — forgive 

 the vivacity of such a word — which may have the gravest 

 consequences." 



I hope that our Society will consent to put these few remarks 

 into print. They seemed necessary to me to point out the 

 true origin of the methods which have just been mentioned, 

 and also to prevent the Germans, if they should in time benefit 

 by these principles, from labelling them " made in Germany."

Pine Weevil (Hylobius abietis) Attack on a 

 Border Estate. 



A wood 36 acres in extent, and consisting principally of Scots 

 pine, a few Douglas fir, spruce and hardwoods, was cut over in 

 191 7. In the autumn of 1922 the area was replanted with 

 Japanese and European larch, Douglas fir, Scots pine, Norway 

 and Sitka spruce, grey and common alder, and ash, with two 

 small squares, one of Thuya gigantea, and the other of American 

 larch. 



At the end of May small beads of resin were observed on 

 some of the plants, and on further examination the large pine 

 weevil {Hylobius abietis) was found to be at work. 



Traps were laid down as soon as the pest was observed. 

 These traps consisted of billets of Scots pine, or larch, 2 to 

 3 feet in length, and 3 to 5 inches in diameter. On one 

 side of the trap a strip of bark was peeled off, and the trap 

 laid on the ground with the barked strip downwards. These 

 traps were examined daily, the weevils being found lying on the
