Read it through once

What an enthusiast he was in cattle! At the bare name of a bull or a cow, his eye would light and his eloquent tongue would turn itself loose. As long as I would walk and listen, he would walk and talk; he knew all breeds, he loved all breeds, he caressed them all with his affectionate tongue. I tramped along in voiceless misery whilst the cattle question was up; when I could endure it no longer, I used to deftly insert a scientific topic into the conversation; then my eye fired and his faded; my tongue fluttered, his stopped; life was a joy to me, and a sadness to him.
