In reply to the inquiry made about this article in The Gardener's Monthly of November last (page 329), we can say that we re-introduced this very old Dutch method of cultivation some years ago. We exhibited collections of Antipodean Hyacinths at the horticultural shows at Haarlem and Utrecht, in 1874, and got large silver medals as first prizes. Again we showed two collections at Haarlem in 1875, and got the first and the second prize. Both the lots exhibited at the last international spring show at Amsterdam (1877) which got the first and second prize, came from our nursery. These lots seem to have attracted very much the attention of the visitors - at least they were spoken of in various horticultural periodicals, and illustrations given of such pairs of Hyacinths cultivated in a double glass, in the Gardener's Chronicle, 1877, page 591, and the Gardener's Magazine, 1877, page 262. Both these illustrations, however, are not correct as to the form of the leaves.. Of these you find an exact figure (No. 47 page 113) in our German catalogue, 303 C. An English edition of this catalogue is in preparation.. In the said catalogue you find some details as to the management of this method of culture, which you will find differ evidently of what is said about the matter in the Gardener's Magazine, 1877, page 261, and the Gardener's Chronicle, 1877, page 632. Till now no other house here seems to have made a specialty of this method of culture.
We have always ready a number of double glasses to suit our customers. The form of these presently used is a perfection (at least as concerns a legacy) of the old Dutch forms which we used half a century ago, when the under part had an inverted funnel form, in which there was more and better room for the flower of the so-called antipodean bulb to develop itself In the new form it sometimes occurs that the flower develops so long, that it is obliged to bend upwards with is top to find room.
This method of cultivation, to be done well... claims much attention, but gives, by the extraordinary effect, no small satisfaction.
We suppose the above particulars will be sufficient to clear up this matter.
