The mail arrived at noon and sunset each day, being brought by "the captain," an aged member of an historic New Hampshire family. The captain was often accompanied by his good wife. She was a motherly creature, and both were prime favorites at camp. The captain had served his country in the war, and had many a yarn to spin. The camp dog was a splendid Newfoundland named Duke, and he was the champion swimmer. Two of the campers had cameras and took photographs, which they sold at good profit. We were often visited by city people boarding at some one of the farmhouses within a radius of ten or twelve miles. Some of these visitors came often, and apparently found considerable satisfaction in observing the details of camp life. Some of us knew a number of Boston and New York people at one of the most popular of these boarding-houses, and one day these friends gave us a most enjoyable entertainment, consisting of a lawn-party, a tennis tournament, and a supper. At another time, we went to a sheet-and-pillow-case party at the same place. Later on, some friends at another boarding-house delighted us with a series of tableaux and charades, followed by supper. [Illustration: THE MORNING PLUNGE IN THE LAKE.] Several business partnerships were formed among the boys. Contracts for work were awarded to the firms making the lowest bids. The successful bidders would hire other boys to help them. The specifications had to be strictly observed. Among other things, a new wharf was built, one of the cabins shingled, and another covered with tar-paper. Boys could do as they pleased with money earned in this way. Idleness was not popular. One fine day, we took a long tramp up Mount Monadnock. An early start was made, and by noon we had covered more than half the distance. Halt was ordered in a shady grove, and before long our wagon arrived with blankets, rubber coats, cooking utensils, provisions, and various tools. We had a substantial lunch while resting on the banks of a pretty brook, before we resumed our march.
