UNDER THE EASTERN HILLS. THE ROUTE. _From the Piazza del Popolo we take the left-hand street, the Via Babuino._ The new English church of All Saints is on the right side. At No. 89, _on the left_, lived Valadier. _We now reach_ THE PIAZZA DI SPAGNA. This square may be considered as the centre of the English and Americans in Rome. Here they come for most of their requirements, and here a great many live. At No. 1, _the corner_, is the well-known Piale's library and reading-room, the most extensive in Rome, where one may find any information that he requires as to what is going on in the city, and, through the newspapers, what is passing at home. Monti, the poet, lived at No. 9. Mr. Hooker's American Bank is No. 20. Shelley lived at No. 25; and Keats at No. 26, the right-hand corner house, by the steps, where an inscription has lately been put up. This square once formed part of "an artificial lake made by Domitian for the representation of naval fights. The fleets were as numerous as those employed in real engagements" (Suetonius, "Dom." 4). [Illustration: FOUNTAIN OF TREVI.] The principal objects are the fountain LA BARCACCIA, by Bernini, at the foot of the Spanish Stairs. It is here that the model and flower girls most do congregate. The column of the IMMACULATE CONCEPTION, found in the Campo Marzo, is supported by statues of Moses, David, Isaiah, and Ezekiel. Its summit is crowned by a statue of the Virgin, in bronze, designed by Poletti. It was erected in 1854. _Beyond_ is the Collegio di Propaganda Fide, founded in 1662 by Gregory XV. _Taking the streets on the right of the Propaganda_, VIAS PROPAGANDA _and_ S. ANDREA DELLE FRATTE, _then the_ VIA DEL BUFALO _on the right, turning into the_ VIA POLI _on the left, brings us to_ THE FOUNTAIN OF TREVI,
