To be sown and cultivated like the Lambertiana cypress.
Tulip Tree, or Whitewood, Liriodendrum tulipifera, L.—From North America, where it attains a height of 60 metres by 3 and 4 metres in diameter. Gives good wood and appears suitable for growing in tall woods on deep and humid soil in regions 4, 5, 6 and 7.
To be sown thickly in furrows or in beds for transplanting when a year old.
Pine Trees.—We already have different kinds of pine trees which flourish in woods. It would be well to introduce the better species, because we lack such as Pinus australis, Michx., from Carolina and Florida, where it grows to 35 to 40 metres in height. This is the species which gives the timber known as pitchpine.
P. Benthamiana, Hartw.—From California. 70 metres in height by 2 metres in diameter. Good timber.
P. excelsa, Wall.—From the Himalayas. 40 metres in height.
P. Jeffreyana, V. H.; P. Lambertiana, Doug.; P. Sabiniana, Doug.; and P. Torreyana, all from California.
P. Strobus, L.—From North America. A hardy tree 40 metres in height by 1 metre in diameter.
The Californian species might be tried in the 4th, 5th, 6th and 8th regions. The Himalayan species on the mountain ranges of the 2nd, 3rd, 4th and 5th, and the last-named species in the 5th, 6th and 8th. That from the Carolinas might be grown together with P. insignis.
