[Footnote 1: _Antheroea mylitta_, Drury.] Towards the northern portions of the island this valuable species entirely displaces the other, owing to the fact that the almond and _palma Christi_ abound there. The latter plant springs up spontaneously on every manure-heap or neglected spot of ground; and might be cultivated, as in India, with great advantage, the leaf to be used as food for the caterpillar, the stalk as fodder for cattle, and the seed for the expression of castor-oil. The Dutch took advantage of this facility, and gave every encouragement to the cultivation of silk at Jaffna[1], but it never attained such a development as to become an article of commercial importance. Ceylon now cultivates no silkworms whatever, notwithstanding this abundance of the favourite food of one species; and the rich silken robes sometimes worn by the Buddhist priesthood are still imported from China and the continent of India. [Footnote 1: The Portuguese had made the attempt previous to the arrival of the Dutch, and a strip of land on the banks of the Kalany river near Colombo, still bears the name of Orta Seda, the silk garden. The attempt of the Dutch to introduce the true silkworm, the _Bombyx mori_, took place under the governorship of Ryklof Van Goens, who, on handing over the administration to his successor in A.D. 1663, thus apprises him of the initiation of the experiment:--"At Jaffna Palace a trial has been undertaken to feed silkworms, and to ascertain whether silk may be reared at that station. I have planted a quantity of mulberry trees, which grow well there, and they ought to be planted in other directions."--VALENTYN, chap. xiii. The growth of the mulberry trees is noticed the year after in a report to the governor-general of India, but the subject afterwards ceased to be attended to.] In addition to the Atlas moth and the Mylitta, there are many other _Bombycidoe_ in Ceylon; and, though the silk of some of them, were it susceptible of being unwound from the cocoon, would not bear a comparison with that of the _Bombyx mori_, or even of the Tusseh moth, it might still prove to be valuable when carded and spun. If the European residents in the colony would rear the larvæ of these Lepidoptera, and make drawings of their various changes, they would render a possible service to commerce, and a certain one to entomological knowledge.
