Tlie usual amount of anoiIc of a iniseellaueous character has come to 

 the chemical laboratoi'v, analysis of marls and coals, the examination 

 of numci-ous specimens of matei-ials that strike the eye of the observer 

 and dill'er from the usual soil materials. Among' these a large number 

 of decomposed granite, showing the glittering particles of mica so easily 

 mistaken for gold. The laboratoiy seems to be a burcnui of general 

 iuformarion for 1lie jnihlic. 



A NEW DOOK OF ISEFLEN ESS. 



Tlie Chemical l)e]»aiiuien1 is ever desirous of finding \u'\y ways by 

 which it may Itent^fit the farming class. A new door of usefulness opens* 

 befoi-e ii in I he valuation of commercial cattle foods. It is not necessary 

 that all such materials should be analyzed. For a large body of such 

 materials the good judgment of the cattle feeder is sutticient. The 

 food value of whole grains and I he meals produced from them is evident 

 1o every stock feeder. The judgment is not so simple when the residues 

 and b.\-]tioducts of such grains and seeds are offered in the form of 

 hulls, hians and mixed feeds. The miller and manufadurer usually 

 remoNcs the most Aaluahle and costly material, and the residui' is often 

 deficient in ]»rotein aud fat, but contains an excess of carbonaceous 

 matei-ial of a cheajx'r grade for sloek feeding. This is not always tli<' 

 case, but is true as a general rule. 



The true value of such byiiroducts caiiuot be deleruiiued by mere 

 inspection: they vary widely in value and availability; they are not ac- 

 (Miraiely measured by the jtrice. for two sauiples of hulls of similar 

 apiiearance demaud the saiue jirice. y<'i dilTer l»y fifty ])er cent in real 

 vabu'. Jn such case the chemist may render the stockman \aluable 

 assistance. 



'I'lie increasing coiisum]»tion of such by |iroducts of mills and factories 

 aud the intrttduct ion of other slock feeds f<a- whirh e.\l laordiuary value 

 is claimed, nuil<e it desirable that the stock feeder secure information 

 which may assist him in <letermining their real value, in many states 

 the analysis of sndi jtroducts is systematically done and iln- composition 

 is branded upon eveiy ]iackage otVei-ed for sale. In such way tin* stock 

 feeder has scuue assurance <tf the value of the material he bu_\s. 



At the meeting of the .Michigan Dairymen's Association last winter 

 the subject was discusse<l and the inijiortamc of such analysis was
