Advantages: Rapidity, immediate and permanent stability, economy of labour, simplicity o£ appliances. This patent foundation is driven forcibly into the earth, by an internal rammer, without digging or boring. The operation occupies but a few minutes, and takes but one-fourth, of the labour usually expended in the erection of poles and posts. This system compresses the earth (instead of loosening it as is the case in digging for a foundation), and the pole can be put into immediate use as soon as erected. Eastern Gallery. 140 .—G. C.
