L AWES' AND GILBERT'S EXPERIMENTS. 129 



It is very evident that bran, fed in a large quantity, or 

 with a small proportion of other food, is a very indiffer- 

 ent food for pigs. It is too bulky, in proportion to the 

 nutriment it contains. The pigs were weighed every two 

 weeks, and it was so obvious after the first weighing, that 

 the pigs in pens 9 and 10 were not getting food enough 

 (though having all the bran they would eat), that the 

 limited food was increased to 3 Ibs. per pig, per day, in- 

 stead of 2 Ibs. But, even with this addition, it is clear 

 that the pigs did not get sufficient nutriment. Their 

 stomachs were not capable of holding enough of this 

 bulky, and probably rather indigestible, food. 



The pigs in pens 9 and 11, ate precisely the same amount 

 of bran per week, but the pigs in pen 11 were allowed 8 3 1 4 

 Ibs. of meal more than pen 9 ; and it will be seen that this 

 8 3 | 4 Ibs. of extra meal produced over 3*| 4 Ibs. of extra 

 increase. 



Comparing pen 1 with pen 5, it will be seen that the 

 pigs having pea meal alone, gain over 3 Ibs. a week more 

 than those having Indian meal alone ; but the pigs in pen 

 1 ate more pea meal than the pigs in pen 5 did of Indian 

 meal, and the actual increase from the food consumed is, 

 if anything, rather in favor of the Indian meal. It will 

 be found that 100 Ibs. of pea meal produce 20 Ibs. of in- 

 crease, while 100 Ibs. of Indian meal produced 20.3 Ibs. 

 increase. It would seem from this that 100 Ibs. of peas 

 will not produce any more pork than 100 Ibs of corn. At 

 the same time, it would seem that pigs will grow or fatten 

 faster on peas than on corn. They are capable of eating 

 more peas than corn. 



By comparing pens 2 and 6, we have the same general 

 indications. In pen 2, the pigs had pea meal ad libitum, 

 and 2 Ibs. of corn meal each, per day; while in pen 6, 

 they had Indian meal ad libitum, and 2 Ibs. of pea meal 

 each, per day. Pen 2 ate the most food, and gained the 

 most rapidly. But still the amount of food required to
