The result verified his conjecture.

The circulation of the sap was arrested, the vines obtained the needful repose, and the grapes, which before had fallen almost unformed from the tree, are now brought to thorough maturity, though inferior in flavour to those produced at home.[4] [Footnote 1: In the Malayan peninsula the bamboo has been converted into an instrument of natural music, by perforating it with holes through which the wind is permitted to sigh; and the effect is described as perfectly charming.

Mr.Logan, who in 1847 visited Naning; contiguous to the frontier of the European settlement of Malacca, on approaching the village of Kandang, was surprised by hearing "the most melodious sounds, some soft and liquid like the notes of a flute, and others deep and full like the tones of an organ.

They were sometimes low, interrupted, or even single, and presently they would swell into a grand burst of mingled melody.

On drawing near to a clump of trees; above the branches of which waved a slender bamboo about forty feet in length, he found that the musical tones issued from it, and were caused by the breeze passing through perforations in the stem; the instrument thus formed is called by the natives the _bulu perindu_, or plaintive bamboo." Those which Mr.Logan saw had a slit in each joint, so that each stem possessed fourteen or twenty notes.] [Footnote 2: See _ante_, p.
