I went back to my conversation with Siegfried that morning
 we had just about decided that the man with a lot of animals couldn't be expected to feel affection for individuals among them. But those buildings back there were full of John Skipton's animals - he must have hundreds. Yet what made him trail down that hillside every day in all weathers? Why had he filled the last years of those two old horses with peace and beauty? Why had he given them a final ease and comfort which he had withheld from himself? It could only be love.
