of timber producing trees, it should form a large proportion of 
any mixed plantation. 
An average of 3500 plants is sufficient for an acre, and the 
following would form a very good mixture :—

These plants should be what is known as two-year, one year 
transplanted, and would not cost more than £3, 5s. per acre. 
That this mixture would be suitable for the whole island is 
certainly impracticable, but for a large part it would be quite 
appropriate, grouping the kinds as required. 
While this table is given as a guide, it should by no means be 
practised over the whole breadth of the island, where planting 
can be executed with profit. Generally speaking, where the 
herbage permits, nothing larger should be planted than two-year 
seedlings, silver fir excepted. In the exposed situations having 
light sandy soils, plant Pinus Pinaster and P. Laricio ; where the 
soil is light and thin, among rock debris, in crevices, and such 
places, sow such seeds as are suitable for the spot, giving of pine 
seeds 2} lbs. to the acre, mixed with the seeds of the broom to 
make them spread properly. Seeding is the most natural, and 
under certain circumstances the least expensive method of stocking 
the ground, with the best results. Next to seeding comes seedling 
plants, either one or two years old, the good results from which 
are assured by the woods that have been cut down during the 
early part of the present century. The least profitable of all 
methods is the transplanting of large plants; the future growth 
and ultimate success of the trees so planted being governed by the 
size and age at which they were transplanted. The less frequently 
forest trees are handled, the less liable are they in after years to 
fall victims to diseases of the roots, and other ills now so 
prevalent. 
Taking the island as a whole, a large part of it could be
