Ground well ventilated and drained. Stable manure used.
Grown in hot-house and transplanted. Some of the tubers were full size. Sown in April, transplanted in June. No disease; but a few tubers were eaten by earth- worms and slugs, I think the tubers will take the disease in the course of two or three years (see Mr. W. G. Smith's report on the potato fungus.) [This report is reprinted in full above, J. T.] Some of the plants had very small foliage, and almost all flowered. A few had seed-apples, but they did not come to maturity. One, a white kidney, (the best of the fine sorts) was very small in the foliage.
Seedlings were grown just beside diseased potatoes. Locality well ventilated. Farm yard manure used. Those planted in March grew larger, and resisted disease better. About eighty or ninety plants per hundred absolutely resisted the disease. Of the plants infected, about one tenth by weight of the tubers was infected. I have seedlings of three years' age which give as large or a larger yield than the set.
Soil good rich clay with sand. Well ventilated. Stable Manure. Grown in field and thinned out. Sown 17th March and 15th April. 17th March, no disease; 15th April, disease hardly perceptible. Unimportant portion of the diseased tubers was infected. I believe that the seed when properly cultivated gives a larger yield than the varieties now grown from the set. I believe the disease may be extinguished by the means you propose. I think the Government should take it up.
"The seedlings were grown in boxes in my green-house in March, afterwards potted, afterwards planted out. About 9 out of 10 plants absolutely resisted the disease. Of the plants infected most of the tubers were infected. There were about 20 to 30 tubers per root (or seed) about as large as walnuts. I believe the set gives a' larger crop than the seed. I think the disease is atmo-
