the existing canopy of an old wood where the trees will soon be removed. 

 The black walnut requires strong sunlight for its successful growth, yet lateral 

 protection is necessary during the first few years. Heavy shade is hurtful, as it 

 hinders the ripening of the wood of the shoots. The black walnut, after it has 

 successfully passed the dangerous period of youth, becomes perfectly hardy ; and 

 older plants resist both spring and winter frosts. Schwappach advocates close plant- 

 ing, with beech or hornbeam as nurses, and recommends thinning at 1 5 to 20 years 

 old, to remove badly-shaped trees, and to give more light to those which are destined 

 to remain.^ 



In France Henry has seen a small plantation of black walnut near Annecy ; but 

 the results obtained were unsatisfactory, as the young plants had suffered much from 

 frost. M. Parde,' however, strongly recommends its cultivation, and points out that, 

 unlike the common walnut, it can be grown as a forest tree ; and states that at Les 

 Barres it sows itself regularly and abundantly. 



Remarkable Trees 



The largest tree which we know of in England is growing in the London County 

 Council public park of Marble Hill, Twickenham, in rich alluvial soil close to the 

 Thames. It was measured by Sir Hugh Beevor and Dr. Henry in August 1905, 

 and the height was found to be 98 feet, the stem girthing at 5 feet up 14 feet 3 inches. 

 The bole is about 18 feet long, dividing into two great limbs, with large spreading 

 branches, forming a beautifully symmetrical crown. The diameter of the greatest 

 spread of the branches was 93 feet (Plate 76). 



Perhaps the next finest tree now standing in England is the one which I figure 

 (Plate ']']), and which grows on a bank at The Mote, near Maidstone, the property 

 of Sir Marcus Samuel, Bart. I have twice measured this tree, first in 1902, when I 

 made it 103 feet by 12 feet in girth, and again in 1905, when I made it loi feet by 

 12 feet 6 inches. I am informed by Mr. Bunyard of Maidstone that it was probably 

 planted about 100 years ago by his grandfather. The tree is so healthy, and 

 apparently growing so fast, that it may become very much larger than it now is. 

 At Gatton Park, Surrey, the seat of J. Colman, Esq., there was, in 1904, a tree 

 about 100 feet by 9 feet 6 inches in girth, with a very tall, handsome trunk. 

 Another at the same place, which, when I saw it, was lying on the ground, was 

 about 95 feet by 9 feet, with a bole 10 feet long, and, according to the measurement 

 given me by the late Mr. Cragg, agent for the estate, contained 315 cubic feet of 

 timber. 



At Highclere, Berks, there is a fine tree 90 feet by 9 feet 6 inches ; and at Bute 

 House, Petersham, Henry measured one 78 feet by 11 feet 10 inches in 1903. At 

 Burwood House, Surrey, Col. Thynne has measured a tree, which I have not seen, 



• Mr. John Booth of Berlin, who has for many years been one of the best advocates for the planting of exotic trees f"r 

 timber, tells me that the black walnut hai; been largely planted near Strassburg under the direction of Forstmeister Rebmann, 

 and the results are extremely successful.
