Today we are going to take a stroll up one block of Devonshire Street; and although it will be a short stroll, it will be a long article, because almost every single house on this block is an extraordinary mansion by some distinguished architect. Old Pa Pitt regrets that he does not know which architect for most of them, but he is feeling lazy today and has decided not to spend the rest of the day researching the histories of these houses. Instead, he will simply publish these pictures, which are worth seeing both for the houses themselves and for the poetic effect of the late-autumn landscapes, and will update the article later as more information dribbles in.
