EFFECT OF PORTO RICO MOLASSES ON DI- 

 GESTIBILITY OF HAY AND OF HAY AND 

 CONCENTRATES. 



BY J. B. LINDSEY AND P. H. SMITH. 



I. INTRODUCTION. 

 In New England, cane molasses brought in tank steamers 

 from Porto Rico has been freely offered for a number of years at 

 from 12 to 15 cents a gallon of 12 pounds in barrel lots. The 

 material is dark in color but quite satisfactory in quality. It 

 has been found to contain from 20 to 28 per cent, of water 

 (average 24 per cent.), about 3 per cent, of protein (largely as 

 amids), 6 to 7 per cent, of ash, and the balance of sugars and 

 allied substances. The following analyses made at this station 

 represent the composition of three different samples of Porto 

 Rico molasses : —

It may be remarked that two analyses of the ash have shown 

 traces of phosphoric acid and 3.6G and 4.84 per cent, of potash, 

 the latter being by far the most ])r('d()minant ash constituent. 

 Beet molasses has been shown to contain rather more ash than 

 cane molasses.
