Clark manages to write about the methods used extensively both in academic and industrial archaeology in a way that holds the interest of any archaeologist even if he or she doesn't understand the science behind the technique. If the science is of interest it is explained but written in a manner it can easily be skipped by those disinterested. He charts the history of archaeological survey from General Pitt-Rivers's hitting the ground with hammers and listening for odd echos right through till today. He also adds the indispensible (for student at least) aid of many examples of where these techniques have and have not worked and importantly why. Whether an amateur archaeologist or a student this book is not only helpfull but also interesting as many science books are not.
