[A] Experiments were made at Belvoir, by Mr. Ingram, in the cultivation of several species of _Agaricini_, but without success, and a similar fate attended some spawn of a very superior kind from the Swan River, which was submitted to the late Mr. J. Henderson. No result was obtained at Chiswick, either from the cultivation of truffles or from the inoculation of grass-plots with excellent spawn. Mr. Disney's experiments at the Hyde, near Ingatestone, were made with dried truffles, and were not likely to succeed. The Viscomte Nôe succeeded in obtaining abundant truffles, in an enclosed portion of a wood fenced from wild boars, by watering the ground with an infusion of fresh specimens; but it is possible that as this took place in a truffle country, there might have been a crop without any manipulation. Similar trials, and it is said successfully, have been made with _Boletus edulis_. Specimens of prepared truffle-spawn were sent many years since to the "Gardener's Chronicle," but they proved useless, if indeed they really contained any reliable spawn.

[C] This has, however, not been confirmed, and is considered (how justly we cannot say) a "canard." [D] This method is pursued with great success by Mr. Ingram, at Belvoir, and by Mr. Gilbert, at Burleigh. [E] Cuthill, "Treatise on the Cultivation of the Mushroom," p. 9.
