 be analysed. To measure the heat in the chamber determines the exact amount of energy giving nourishment there is in that particular food. Since heat is the expression of en- ergy it only remains to measure the heat within the ealorimeter chamber to determine the energy expended by the f"subject' under experiment.. And the measuring is done thus:
 Water pipes in coils, much like those used in heating houses are run through the calorimeter. Cold water, of known temperature runs through them. The water absorbs the heat in the room-that given off by the man within the chamber. The tenn perature of the water as it passed from the room is again taken and the the amount of heat or energy gener- ated from the food under test. So closely does the calorimeter register this heat that it's dials show the slight est movement of the subject-such as the raising of arm.
 Tests are made in the chamber with the man at exercise and at rest. In order to know the amount of muscular energy expended a stationary bicycle arrangement is rigged up in the call orimeter. The hind wheel of this is made of sheet copper. Resisting cur rents of electricity are passed through this wheel so that it is known exactly the load against which he pulls.
 There is now known by analysis the constituents of the ash from the food and the energy supplied by it. There remains then the gas or breath test of the breath is made at the same time as the test of the energy. Chem ically measured air is passed into the chamber. The breath is known to give off two properties from the food digest and carbon dfoxide.
 When the air is drawn from the chamber it is passed through su1phuric acid to extract the moisture and through soda lime to extract the car bon dioxide. These two chemicals are analysed after being saturated with have been given off in the breath from the food consumed are deter mined.
 By simple process of elimination the constituents of the ash, the breath and the energy amount being 1 subtracted from the original anayl- 1 portion of the food was retained by l the system and went to maintaining | or building up the frame.

 Very soon the United States will have enough batt1eships to maintain on the Pacific, as well as on the At lantfc, a fleet of no mean propor- | tions. Since the voyage of the fleet around the world a number of the old CT battleships have dropped out and given place to new ones. The Nebras- ka and Wisconsin were added before the journey was completed. Since then the New Hampshire. Mississir- pi, and South Carolina have taken tneir places in the line. The Delaware and nissioned. The Florida is about to be launched at the Navy Yard at New York and will be followed in a short time by the Utah. When the Arkan- sas and the Wyoming, now building are completed, and the two batt1eships which will probably be provided for oy the present Congress slide from 5he ways for the finishing touches here will be- few ships of the original feet which went around the world eft in the first line.
 Before the end of the present year t will be possible to place in comrlis- sion 8 fleet of twelve battleships on he Pacific without touching the six cen battleships of the Atlantic fleet. They are the Missouri, Alabama, Ohio, Kentucky, Illinois, Maine md the four battleships dating from he apnish-American war-the Indi- ma, Massachusetts. Oregon and Iowa. Some of these ships went around the world and are still first class fighting 1 hips. Altogether they would consti- | ute a force of such strength that no ieet after crossing the Pacific, could l lttack them with impunity or take my chances with them. What to do with theses ships is one | if the questions that is beginning to l ,erp1ex the Navy Department. They flowed to deteriorate, although none
