[My garden in July]
A garden...teems with life. It glows with colour and smells like heaven and puts forward at every hour of a summer day beauties which man could never have created and could not even, on his own resources, have imagined... when the garden is in its full glory the gardener's contributions to that glory will still have been in a sense paltry compared with those of nature. Without life springing from the earth, without rain, light and heat descending from the sky, he could do nothing. When he has done all, he has merely encouraged here and discouraged there, powers and beauties that have a different source.
