Notes and Queries. 



[Under this heading we propose to insert short questions and answers 

 On all topics connected with Forestry, &c. We shall be glad of the co-opera- 

 tion of our readers in answering questions, as it is believed that by this means 

 much useful knowledge may be diffused. — I^b. J. F.] 



Coxes os- Wellingtoxia Gigantea. — There are cones on a tree of 

 the Wellingfonia giganiea here this season. Is this anything new? — N. 

 Craig, An-owc Park Estate Office, Bb-lcenhcad. 



No, but still not common.— Ed. /. F. 



H.M.S. " Caledonia," &c.— Has either PI.M.S. Calcilunia, Tenedos, or 

 spartan been opened for repairs since 1875, the date of publication of 

 Laslett's " Timber and Timber Trees ;" and if so, what evidence have they 

 afforded as to M. de Lappurent's carbonizing process? — G. S. B. 



Clearisg Plaxtatiox Grouxd.— Would any of your readers kindly 

 inform me what is the best and cheapest method of converting old planta- 

 tion ground into arable land ? AYhat would be the cost per root (or 

 stump) of using one or other of the following explosives ?— Dynamite, 

 Tonite, or Gunpowder ? What should be the cost per square yard for 

 trenching nine inches deep and removing all roots, there being few stones 

 in the ground ? The roots are all Scots fir ; the trees were sixty years 

 old, and cut down eight j ears ago. — M. R. 



Luminous AVood. — T should be glad if any of your correspondents 

 could give me some information concei-ning what is here called luminous 

 wood, — the cause of its appearance, and whether some species of trees are 

 more addicted to it than others. The other day, on iq)rooting the stump 

 of a spruce fir that had Ijeen cut down some years ago, parts of it presented 

 quite a phosphorescent appearance in the dark, so much so that one could 

 almost read a book by the clear bright light given off by the phosphoric 

 wood. An Irish workman tells me it is a common occurrence in some parts 

 of Ireland. — Y. Herbert, CljilMy McmnoutJisJdre.
