 Baron von Kottwitz recommends shortening the young 

 shoots of seedUng ahnonds in autumn, which, he thinks, stops 

 the sap sooner, and thus renders them safer against the frosts ; 

 they also begin to grow sooner in spring. He also mentions 

 having raised almond trees from cuttings of the roots. 



41. Experiments made by M. Harttveg to ascertain •which Sort of 

 Wood is most jit for Stakes, in ixihich he shoivs hotv long the differ- 

 ent Sorts lasted. 



Class 1. Resinous woods, such as Pinus, &c., after being 

 seven years in the ground were not at all rotten. 2. Robinm, 

 &c., were about one sixth or one half rotten in that time. 

 3. C/lmus, &c., were entirely rotten. 4. ^^cer, &c., rotten 

 after five years. 5. ASalix, &c., after four years. 6. Car- 

 pinus, &c., after three years. 



42. Meeting of the Society, Sept. 7. 1828. 



M. Furstenau manures his cabbages, before they close their 

 heads, with sheep-dung round the stems, which occasions 

 them to grow very large and firm, and also to keep better. 



M. Ohlendorf, at Hamburgh, communicated to the Society 

 his observations on sowing plum stones. When perfectly 

 ripe, they are, without being divested of the flesh, sown in 

 beds in the autumn. The same is practised with cherry stones, 

 with which he succeeds equally well. M. Lenne observes 

 that the principle of sowing stone fruit is, not to let the 

 stones become dry, wherefore they should be either sown 

 directly when gathered, or preserved in moist sand during 

 the winter; and M. Otto adds, that he has observed that 

 stones from fruit which are injured by maggots never ger- 

 minate. 



45. On the Origin of Weeping Trees. By Mr. William Anderson, 

 Curator of the Botanic Garden at Chelsea, near London. 



" I have never seen a printed report on the manner in 

 which the different varieties of trees have been discovered ; for 

 example, the weeping ash. The cause of this neglect may be, 

 that persons finding such varieties either do not examine their 

 origin, or keep it secret, from personal interest. If, therefore, 

 this subject be not better known in Germany than in England, 

 the following observations may prove not uninteresting to your 

 Society. Fascicles or bundles of shoots are often observed 

 on trees, which resemble a bird's nest at a distance ; but, when 

 examined, they prove to be a cluster of small twigs. Such 

 bundles are observed on different trees, but more frequently
