The Rooting of Poplar Cuttings. 



In most estate nurseries a stock of poplars is raised for 

 planting in moist hollows and similar suitable places. Some of 

 the species, and especially all the Balsams, are easily raised, 

 but others such as P. canescens are somewhat more difficult 

 to strike. Taking a lead from certain investigations on the 

 influence of acids on the rooting of cuttings, an experiment 

 was tried with poplar cuttings. The species planted were 

 P. canadensis^ P. deltoidea^ and P. canescens. The soils in which 

 the cuttings were placed were, in one case, loamy sand, and in 

 the other loam. The cuttings were inserted in autumn in the 

 usual manner. On the soil between the lines was placed a 

 thin layer of leaves. Later, about March, a layer about \\ inch 

 thick of undecomposed, black and acid leaves from a ditch was 

 placed above this, and then, except for weedings, the cuttings 

 were left alone. Control lots were kept. The results obtained 

 were satisfactory. Of the P. canadensis, practically all the cuttings 

 rooted, and the difference due to treatment was negligible; 

 of the P. deltoidea, the difference was greatly in favour of the 

 mulched cuttings; while in the most unsatisfactory poplar to 

 root, P. ca?iescens, the results were overwhelmingly in favour of 

 mulching. The experiment will be repeated if possible, in order 

 to find out how far the results are affected by variations in 

 rainfall and factors of that kind. The experiment may also be 

 tried with other plants. 



Moray and Nairn Foresters' Society. 



It will interest readers to learn that the foresters of Moray 

 and Nairn have struck out in a new direction by forming 

 themselves into a Foresters' Society. The membership is 

 confined to foresters and forest workers, and the Society is 

 already over eighty strong. The annual subscription is quite 

 small, and is graded to four classes of member. The president 

 is Mr Matthew Feaks, Darnaway, and the other office-bearers 

 include many whose names are well known in Scottish forestry. 

 The Society is fortunate in having for its secretary and 

 treasurer Mr John M'Ewen, Monaughty Forest, by Elgin. 

 The objects are social and educational. In summer, Saturday
