John Flood had a room at the bottom of the hill near the shooting range, and as far as I remember we always went there to be taught by him, instead of staying in our normal classroom.
According to the 1968 Stouts Hill Magazine, he taught science, geography, and scripture, thereby covering a considerable amount of ground. I don't remember whether he taught me scripture, but (coming from a non-religious family) I was never very receptive to that subject. I do remember that we touched on the subject of biology once — and we went to the lake to look for specimens — but I think that was only for a short period of time.
He was mainly memorable for taking us sailing. On Sundays he would take a few senior boys in his car to Frampton, where we sailed on a lake that was part of a wildlife sanctuary. The lake wasn't very large, but it was larger than the school's own lake, and had a couple of islands in the middle, which made it more interesting. We used to hope for bad weather, because in good weather there was no wind and we'd have to paddle slowly around the lake.
Apart from the sailing, the other attraction of Frampton was the packed lunch, which was different from regular school food and therefore greatly enjoyed.
Mr Flood had a small printing press with movable type, which was used to print some notices for the school. Boys who felt interested could participate in using it.
It was kind of him to give up his Sundays to take us sailing, and we appreciated it as a treat at the time. I was a bit wary of him because he came down rather sharply on any misbehaviour; but I suppose that's fairly normal for schoolmasters.
I wrote to Mr Flood in December and received a long and pleasant reply in January, most of which I've added as a comment to this post because it seems too long to add as an indented quotation. He seems to have prospered well enough over the years.
