We left this highway at Chelmsford to visit the Greenstead Church near Chipping-Ongar, about twenty-two miles from London. This is one of the most curious churches in all England. It is a diminutive building, half hidden amidst the profusion of foliage, and would hardly attract attention unless one had learned of its unique construction and remarkable history. It is said to be the only church in England which is built with wooden walls, these being made from the trunks of large oak trees split down the center and roughly sharpened at each end. They are raised from the ground by a low brick foundation, and inside the spaces between the trunks are covered with pieces of wood. The rough timber frame of the roof is fastened with wooden pins. The interior of the building is quite dark, there being no windows in the wooden walls, and the light comes in from a dormer window in the roof. This church was built in the year 1010 to mark the resting place of St. Edmund the Martyr, whose remains were being carried from Bury to London. The town of Ongar, near by, once had an extensive castle, of which little remains, and in the chancel of the church is the grave of Oliver Cromwell's favorite daughter. A house in High Street was for some time the residence of David Livingstone, the great African explorer. From Chipping-Ongar we followed for the third time the delightful road leading to London, passing through the village of Chigwell, of which I have spoken at length elsewhere. On coming into London, we found the streets in a condition of chaos, owing to repairs in the pavement. The direct road was quite impassable and we were compelled to get into the city through by-streets--not an easy task. In London the streets do not run parallel as in many of our American cities. No end of inquiry was necessary to get over the ten miles after we were in the city before we reached our hotel. It was not very convenient to make inquiries, either, when driving in streets crowded to the limit where our car could not halt for an instant without stopping the entire procession. We would often get into a pocket behind a slow-moving truck or street car and be compelled to crawl along for several blocks at the slowest speed.
