In order to make a fairer comparison of the composition of the dr>- 

 material, the average results, as shown in table on page 58, have been 

 calculated to a water-free basis, as shown in table on page 59. 



The whole pumpkin contains rather less ash than carrots or mangels, 

 although it is much richer in mineral matter than the ordinary grains. 

 The seed is much poorer in ash than the other portion of the fruit. The 

 dry matter of the entire pumpkin contains rather more total protein 

 than roots or grain, with a portion of it in the amido form. The seeds 

 were found to be very rich in true protein. The fiber content of the fruit 

 is noticeably higher than in roots. The seeds have more fiber than the 

 other portion, due to the tough seed coat. Nearly all of the fat is con- 

 tained in the seed, the analysis of the two samples showing an average of 

 37.49 per cent. The pumpkin contains large amounts of sugars; in the 

 entire fruit one notes nearly 18 per cent., of which substantially one-third 

 is in the form of cane sugar, while in the portion free from seeds 42.52 per 

 cent, total sugars are noted. While sugar was not determined in the 

 seeds, it is evident that they contain Uttle, being made up chiefly of 

 protein, fat and fiber. 



Ulbricht ^ and Hills " made analyses of the ordinary field pumpkins, and

 following results: —
