The fact that the leaves and twigs, as well as the wood of the camphor tree, yield camphor where the variety experimented with is the right one, has also been definitely settled. In a recent examination at the Government Laboratory of the Leeward Islands of samples of fresh leaves and twigs from trees growing in the Botanic Station, Dominica, one specimen yielded 1"6 per cent, of camphor and only 0 2 per cent, of.oil, while a second specimen yielded 232 of camphor and 0'05 per cent, of oil, and a third yielded no camphor, but 185 per cent, of oil. The last were leaves and twigs from a tree, the seeds of which were imported many years ago, while the first two came from trees grown from seeds of more recent importance. In Jamaica also, the distillate obtained from both green and dried leaves consisted of over 2 per cent, of crude camphor, and in Florida the distillate is said to yield in some cases 277 per cent. Apart from the question of different varieties of the camphor tree, the most suitable environmental conditions for its cultivation are also of importance so as to ascertain in what localities it may be exploited commercially as a profitable industry. In this connexion local agricultural officers will be able to give valuable assistance. The range of the tree is partly tropical and partly subtropical, from about 10 to 30 N. latitude, and there is no reason, why it should not flourish under similar conditions in South latitudes between the same degrees. It is said to flourish best on hill sides and mountain valleys, where there is a moist atmosphere with good drainage. The tree is known to respond well to fertilizers, but apparently it does not flourish on calcareous soils. Siliceous soils or sandy loams suit it best, more
