- PART III.—MISCELLANEOUS MATTER CONNECTED WITH NAVAL TIMBER.
- 106 NURSERIES,
- ib. Infinite variety existing in what is called species,
- 107 Injurious effect from selecting the seed of the inferior varieties for sowing,
- ib. Injurious effect from kiln-drying fir cones,
- 108 A principle of selection existing in nature of the strongest varieties for reproduction,
- 109 Injurious effect from the plants spindling in the seed-bed and nursery line,
- 111 Injurious effect from cutting the roots and from pruning,
- ib. A light soil and open situation best suited for a nursery,
- 112 Wide diverging root-leaders necessary to the large extension of a tree,
- 114 PLANTING,
- 117 Further observations on pruning,
- 122 Observations on timber,
- 124 Table of the number of sap-growths of different kinds of timber,
- 126 Remarks on laburnum,
- 128 Height to which trees may be trained of clear stem,
- 130 CONCERNING 357 That the line of seed ripening, and not the line of growing, regulates the natural distribution of plants in respect to climate,
- ib. That oaks, under this plan of sowing in situ under shelter, can be extended to a climate inferior to the natural,
- 358 That oaks grown in the low country, and best climate of Scotland, appear not to ripen the seed sufficiently. Thence the probability that oak now would not even keep its present locality in the low country of Scotland, although it may “be taught to rise in our” alpine country,
