The results of these enquiries were published in full 

 in No. 21, and less fully in No. 23, on the Composition, 

 Value, and Utilization of Town Sewage. The subject 

 has also been discussed in Nos. 8, 9, 19, and 26 

 (all in Series 2). 



2. Experiments on the Malting Process, and on the Com- 

 parative Feeding Value of Barley and Malt. 



The chemistry of the malting process, the loss of 

 food constituents during its progress, and the compara- 

 tive feeding value of barley and malt, were made the 

 subjects of independent experiment at Rothamsted in 

 1848 and 1849 ; and in 1863 and 1864, a more com- 

 prehensive investigation was undertaken by order of 

 the Board of Trade. The earlier results were discussed 

 in Nos. 1, 4, 12, and 13, and the later in No. 22 (Series 2). 



3. Experiments on Ensilage. 



Experiments were commenced in 1884, and continned 

 for several years, to determine the changes and losses 

 which food-crops undergo in the process of ensilaging, 

 and also the feeding value of the silage produced. With 

 these objects two silos were constructed. 



In the first season, 1884, one silo was filled with first 

 and second crop red clover, and the other with first 

 crop meadow-grass, second crop red clover, and second 

 crop meadow-grass. 



In the second season, 1885, Silo No. 1, was partly 

 filled with oats cut green, when the grain was in the 

 milky condition, and partly with second crop red 

 clover : and Silo No. 2 with first and second crop red 

 clover. 



In the third season, 1886, first crop meadow-grass 

 was put into Silo No. 1 ; and into Silo No. 2, first 

 crop red clover, a mixed crop grown for the purpose, 

 consisting of beans, peas, vetches, and oats, and second 

 crop red clover. 



In the fourth season, 1887, a similar specially grown 

 mixed crop of beans, peas, tares, and oats, was put
