Most people who possess anything like an acre, or half of it, contribute weekly to the support of a gentleman known as Jobbing Gardener. You are warned of the danger that he may prove to be Garden Pest no 1. – C.E. Lucas-Phillips, The New Small Garden
We think that diamonds are very important, gold is very important, all these minerals are very important. We call them precious minerals, but they are all forms of the soil.
