that beset them when they are near the ground. They are also 

 suitable for thrusting in hedgerows and such-like situations. Care 

 should be taken to prevent cattle from injuring the stems. In 

 some places Willows are being pollarded for the especial purpose 

 of producing "sets" of the desired size. But with the present 

 demand for this Willow this seems a slow and cumbersome means 

 of propagation ; slow, that is, to produce a large quantity ; no 

 doubt for the individual tree it may be the quickest. This Willow 

 is one of the most easily propagated of all trees, for every twig 

 will grow. I would recommend the use of cuttings which can be 

 made of any shoots as thick as a goose-quill and, say, 1 foot long. 

 Cuttings of this character, planted in the Arboretum nursery at 

 Kew last spring, are already (in August) 6 feet high. For 

 thicker wood the cuttings may be proportionately longer. These 

 can be put in the ground in autumn or early spring. As 

 they grow it would be necessary to keep them each to a single 

 leader and to prune back the side branches and remove the 

 lower ones as the plants grow in height, In well-kept nursery 

 ground fine healthy plants could be produced in two or three 

 seasons, and they could be grown to planting-out size at the rate 

 of 8,000 or more to the acre. 



Whilst these Willows like abundant moisture, a position by the 

 side of water is not necessary. The fine specimen here illustrated 

 is, with several others, growing in a deep, rather heavy clay, with 

 only an ordinary hedge-row ditch on one side. Mr. Shaw told 

 me he preferred timber grown in such a position to that of trees 

 growing close to the edge of ponds, &c. 



Young trees should be watched to see that they are kept to a 

 single leading shoot. This will obviate the forking of the trunk 

 low clown, which, of course, detracts from the value of the tree 

 by reducing the amount of good timber. Trees, however, are 

 more liable to fork when growing in isolated positions than they 

 are when close together in plantations.
