Blowing Stone

Summary of Proceedings of the Bath Natural History and Antiquarian Field Club for the years 1865-6.
[...] The first [Excursion] of the season, to Wantage, the Berkshire White Horse, and Uffington, was a success in every way, due chiefly to the admirable arrangements made by Mr. Wasbrough for the transit and conveyance of the members. Under this gentleman's guidance the chief points of interest in the birth place of King Alfred were visited [...]. Leaving Wantage the members proceeded in carriages to the foot of the Downs, and essayed a blast upon the blowing stone (a mass of perforated silicious sandstone, said to have been formerly used for sounding an alarm over the neighbouring country).

The united efforts of all Bath were unable to produce a sound from the trumpet shaped hole. A native trumpeter, however, being found was more successful, and satisfied all present that when in its original place on the top of the Downs a most effective alarm could be raised.
