A Problem for Surveyors.—A gentleman who lived in a house on an estate decided that he would divide the estate into five building plots. There were ten fine old trees, and his instructions to the surveyor were: Don’t count my house in the division. I shall have that extra, but divide the remainder of the park into five equal parts with straight boundaries. I shall retain one part for my own grounds. Be careful to arrange that each plot shall have two of the trees. How did the surveyor divide the estate?

How did he manage it?
