PINETUM DANICUM. 



279 



odoriferous resin, satiny, susceptible of a beautiful polish ; layers of 

 small svimmer cells thin, not conspicuous ; medullary rays numerous, 

 very obscure ; colour light yellow or almost white, the thin sap wood 

 hardly distinguishable ; specific gravity, 0*4621; ash, O'lO ; largely 

 manufactured into lumber and used for interior finish, flooring, 

 railway lines, fence posts, matches, and in ship and boat build- 

 ing ; the resin strongly diuretic and a powerful insecticide (Ch. S. 

 Sargent) . 



It was named in compliment to. Mr. Charles Lawson, of Edinburgh, 

 head of the well-known horticultural firm of Peter Lawson & Sons, 

 and, at one time, Lord Provost of the city. 



CJiamsecyparis Laivsoniana is in diflFerent Danish parks and forests 

 to be seen of a height of more than 40 feet. One plant, just now 

 measured, and planted in 1864, has attained a height of 32 feet and a 

 girth of 8 feet 10 inches. 



Young plants sometimes suffer on somewhat low ground, but they 

 are rarely killed. Most beautiful specimens are to be seen in many 

 gardens and forests. In some Danish nurseries seeds from California 

 have been sown, and the result has been that some plants of light 

 colour and less pyramidal growth have not proved so hardy as the 

 more pyramidal seedlings with a more glaucous hue. 



About the Lawson Cj^press Prof. Schiibeler reports in his "Viri- 

 darium," p. 374, that it looks finer than the Cliamgecyparis nutkaensis, 

 but it is perhaps not so hardy. It is to be found in diff"erent places in 

 the South of Norway, but so far as he knows it is not tried farther north 

 than Molde (62° 44'), where it thrives very well. At Horten (59° 25') 

 is to be found a specimen which in September 1871 measured 5 "6 

 metres in height. At Christiansund (58° 8') Prof. Schiibeler has seen 

 the varieties lyyramidalis and erecta viridis. At Christiania (59° 55 ) 

 this species keeps well, but still, he says, it seems not so hardy as 

 C. nutkaensis. 



In the southern parts of Sweden it thrives well as far as Upsala. 

 At Stockholm there was planted out in 1867 a specimen only a 

 few inches high. This plant had in 1884 reached a height of 15 

 Swedish feet, and had for several years produced ripe seeds. 



Writing of the Lawson Cypress, Dr. Dieck, of Zoschen, near 

 Merseburg, says, in the Gartenflora, 1892, Heft v. 122 : "I and some 

 other writers regard it as the tree of the future for the lowland parts 

 of Middle Germany, especially for cemeteries, as, from its sombre 

 appearance, it is very suitable for planting in the ' gardens of the 

 dead.' As is well known, but few specimens of the Oregon Cedar 

 were sufiiciently hardy to survive the severe winter of 1890-91 ; 

 while in many localities — even in Holland — not a single plant could 

 be found that was uninjured by the frost."
