We have also in these publications an admirable paper by Captain Wilson, 'On the site of Ai and the position of the Altar which Abram built between Bethel and Ai;' and another by the Rev. Dr. Zeller, Protestant clergyman at Nazareth, on 'Kefr Kenna.' As the old Hebrew names of places commonly cling to the spot under some Arabic disguise--the hill of Dan, for instance, being now Tel el-Kadi (both Kadi in Arabic, and Dan in Hebrew, being equivalent to 'judge' in English)--it is doing good service to collect Arabic names. Great care, however, is needed in this work, for the same _wady_ may have different names in different parts; two or three hills, a fountain, and several ruins may all have one name--that of the district; and the traveller may misunderstand the Arabic answers to his questions. Mr. Layard tells a story of a traveller, who published, for the benefit of those who might follow in his footsteps, a little vocabulary, but whose own ignorance of the language is shown by the fact that several places on his map are marked with the word _Mabarafsh_. The fact was, that when the traveller asked his guide the name of a place the man answered _Mabarafsh_--'I don't know,' and down went this name on the map. In the same traveller's vocabulary 'nose' is put down as _snuff_; for when he wanted the word for nose he had probably raised his hand, and the Arab supposed he wanted 'snuff.' Under these circumstances, it must have been very satisfactory to Lieutenant Warren, after making a list of 150 places visited or seen on the east of Jordan, to find that wherever Robinson had been before him there was substantial agreement in the spelling. Lieutenant Warren and Dr. Chaplin, of Jerusalem, also obtained many names in the course of a tour from Jisr Damieh to Jisr Mejamia and back; and the former has given us a list of thirty-four Tels in the Jordan valley. More work of the same kind will have to be done, as there is much confusion in the spelling of names; besides which there exist many unnamed cities and ruins on both sides of the Jordan. South of Ammân (the ancient Rabbath-Amman, and afterwards Philadelphia, 2 Sam. xi. and xii.), Lieutenant Warren came upon a piece of elevated country, about four miles square, literally covered with ruins of temples and houses. The synagogue at Capernaum was only one out of nine synagogues examined in the district north of the Sea of Galilee, and the investigation was so thorough that the plan of the building was made out, and careful drawings made and measurements taken. The result has been to dissipate the idea that the synagogues were barn-like structures, and to prove that they had considerable architectural pretensions.
