Mr. A. B. Rundle, of Wangaratta, writes: The 27th day of April, 1908, proved a most eventful day for me. On that day, I won the prize for the best twelve roses at the Euroa show, but, of more importance, I was introduced to the judge – the late Mr. John Cronin. From that time, I became one of his pupils, and it is the passing on of some of his store of knowledge which must take the credit for any success I may have had in horticulture. Mr. Cronin, on one of his holidays at my home, said, “I will tell you how to garden and do it successfully, in a lecture given in two minutes. Now, concentrate that you are standing in a virgin forest. You will be surrounded by trees. Has God or Nature ever trenched the ground? A good farmer only tills his soil 4 to 4½ inches. And with a scarifier farmer only scratches the soil 1 to 1½ inches in the growing season. So why dig so deep? In the forest God or Nature never buries any seed, but He does cover the seed with a layer of leaves. So try covering your seed with a layer of old manure or lawn clippings. Watering should average once or twice a week, but again get back in the forest and hold tight to the average rainfall of your district. The animals of the forest deposit the manure on the top of the ground. The sun and the wind decay the manure and the rain washes the manure into the soil.” I have followed this lecture of Mr. Cronin’s and whenever I get wondering just what to do, I still remember my teacher and get back into the forest.

...then John Cronin with its vigour and health, rather dominates its neighbours. From it I raised Sophie McKinnon really a satisfactory Rose.
