We have not heard much of this new invention which we brought to our readers' attention a year or so ago. But then it takes a long while for really good things to become generally known. The Gardener's Magazine says of it:

" Hardened glass is more often heard of than seen; but the time seems near at hand when we shall see nothing else, for the hardening process has undergone further improvements and amplification. We now hear of railway sleepers made of glass, and all such things as decanters, drinking glasses, and glass ornaments are promised us, not only in the hardened state, but as cheap as the common breakable glass we have been so long accustomed to. How the process will tell on horticultural glass is not as yet clearly apparent, but there is a fair prospect that in future our glass houses will be proof against such objectionable accidents as damage by hail storms and breakage by naughty boys who throw stones. It would be well if the Royal Horticultural Society, or some similarly representative body, would institute inquiries and experiments with a view to inform us what is possible in aid of horticulture by the use of hardened glass. The glassworks of M de Labastie, at Choisy-le-Roi, appear to have obtained a lead in this important manufacture".
