foivgoiiiK •' guanuitecd analyses" are available to all purclra.scrs who request such 

 from sales agents. Whether or not such feeds are uniform in composition or live up 

 to the guaranteed analyses, can be proven only by careful sampling and analysing by 

 a chemist. 



The following analyses were made by Mr. F. T. Shutt, Dominion Chemist, who 

 has done a large amount of work relating to molasses as a foodstuff. The.-e figures are 

 lii'i-c copied to illustrate the above-mentioned comparisons. Readers are particularly 

 referred to complete analyses and explanatory notes as contained in the report of the 

 Dominion Chemist. 



Samples Nos. 1 and 2 were analysed a year ago and reported in the annual report 

 for the year ending March 31, 1913. Samples IN^os. 3, 4, and 5 were analysed during 

 the past year, complete details of which are found in previous chapters of this report. 



Whether or not these meals were representative of their respective brands caimot 

 be said. These, however, were all purchased on the market, and should be representa- 

 tive. 



Comparisons of the above analyses with the results of the feeding experiments are 

 most interesting. Final deductions would be impossible owing to the shortness of the 

 test, yet one most noticeable fact may be noted, namely, in the above experiments the 

 food values of molasses qnd molasses meals are in the same order and i^roportion to 

 their sugar content, while the protein might be largely discarded in calculations as 

 being mostly indigestible. 



MILKIXG MACHINES. 



As reported in the annual report for the fi.scal year ending ]\[arch 31, 1913, con- 

 siderable work has been done at the Central Experimental Farm in connection with 

 milking machines. Although nothing of a definite nature is as yet ready for publica- 

 tion, a brief summary of operations to date is worthy of note. 



In July, 1912, a Sharpies mechanical milker was installed in the main barn of the 

 Central Experimental Farm with an idea of testing thoroughly this method of milk- 

 ing, and this machine in particular, as to its commercial value, its economy, durability, 

 the effect on the cows as compared with hand milking, and particularly on the bac- 

 terial quality of the milk produced. Six milking units of this mechanical milker, 

 together with all necessary equipment, including an electric motor, were installed 

 with a total cost of $1,043. Each milking unit cost $110, with the pump, vacuum 

 tanks, etc., extra. To readers who are not acquainted with milking machines, atten- 

 tion is drawn to the fact that with the Sharpies mechanical milker a milking unit 

 milks only one cow at a time. 



In September, 1913, another make of milking machine, namely, the Burrell-Law- 

 renee-Kennedy, was also installed in the main barn of the Central Experimental Farm. 

 The reason for this installation was to obtain comparative data between the Burrell- 



OlTAWA.
