A pound of preserved blackberries supplies about 1,120 calories of energy, 4 

 grams (about r ounce) of protein, 0.16 gram of calcium, 0.1 gram of phosphorus 

 and 1 milligram of iron. It vs^ould furnish, therefore, 32 per cent of the energy 

 a man needs daily, 4 per cent of the protein, 24 per cent of the calcium, 8 per 

 cent of the phosphorus, and 9 per cent of the iron. This is shown in the 

 following chart:

One pound of lard supplies about 4,100 calories of energy, and, if thoroughly 

 refined, no other nutrients. It would furnish, therefore, 117 per cent, or con- 

 siderably more than all the energy a man needs daily. This is shown in the
