"The interest that has always attached itself to Stonehenge has, without doubt, been in a great measure due to the mystery as to the origin of this unique monument of bygone time. But the careful investigations carried out by the modern school of archæologists, as instanced in the work of General Pitt Rivers, Mr. Gowland, and others, every excavation being carried out with great care and scientific accuracy, have had good results; little by little the history of Stonehenge has been unravelled; a fact that Mr. Stevens has clearly demonstrated in the present volume. We now know how, when, and who, built this remarkable temple. One point, however, still remains a mystery, viz. whence the socalled foreign stones were obtained? Clearly, as geology shows, from no spot in Wiltshire. "
