20 EXPERIMENT STATION. [Jan. 



connection with such work than in 1906. Three hundred and 

 fifty-eight samples in all have been analyzed and nearly 500 

 collected. Forty-one per cent, of the samples analyzed proved 

 to be below the guaranteed composition in some one or more 

 of the fertilizer elements, but in many cases the deficiency in 

 one element was made up by an excess in one or more of the 

 others. Twenty-one samples of complete fertilizers showed a 

 commercial shortage varying from 79 cents to $13.50 per ton. 

 This section of the report of the chemist presents complete tab- 

 ular statements, showing the extent to which the fertilizers 

 analyzed equaled or fell short of the guarantees. 



The next section of the report presents an account of the 

 execution of the feed law. Samples of feeds analyzed, with 

 the single exception of cotton-seed meal, the quality of which 

 was unusually poor, were found in general to be substantially 

 as guaranteed. The report calls attention to the large amount 

 of analytical work which is done without charge for private 

 individuals in determining the quality of samples of milk and 

 feeds. The results of the execution of the dairy law are briefly 

 presented : 6.62 per cent, of Babcock glassware tested was con- 

 demned on account of inaccuracy ; of the Babcock machines 

 inspected, 37 in all, 2 were condemned. 



The chemist calls attention to the great increase in the amount 

 of work connected with the carrying out of official tests of pure- 

 bred cows. Such tests are now conducted with animals of the 

 Jersey, Guernsey, Holstein-Friesian and Ayrshire breeds. 

 During the past year thirty-five yearly records and seventy 

 records for shorter periods have been completed. Sixty-three 

 cows are now undergoing tests. This work consumes a large 

 amount of time, and, while the station is reimJjursed for its 

 money expenditure, it is found to be somewhat of a bm'den. 

 The work is, however, without doubt important and useful, and 

 until it is provided for in some other way the station will con- 

 tinue to supervise it. 



The report of the chemist briefly presents the results of ex- 

 periments completed with a view to determining the value for 

 different classes of live stock of molasses and molasses feeds. 

 He does not regard molasses as possessing advantages for dairy 

 cows over the more common feeds. For fattening cattle, the
