Control Activities of the Experiment Station. 

 In addition to its main functions of a research agency, the Experiment Station 

 administers four control laws, namely, providing for chemical control of commercial 

 feedstuffs sold within the State, and of commercial fertiUzers and lime, providing 

 for the testing of poultry for bacillary white diarrhoea, and inspection of dairy 

 glassware. In the first three of these, which are the major control activities of 

 the Station, reports were published covering the operations of both 1925 and 1926. 

 Further comment on this phase of the work is not needed at this time. 



Increase in knowledge regarding the properties of certain agricultural com- 

 modities, and conditions governing their effective use, make necessary three changes 

 in existing control laws, as follows: 



1. The great increase in the use of cod liver oil and other vitamin carriers, in 

 both animal and human nutrition, makes necessary a form of guarantee under 

 which they may be sold, different from any which has previously been in common 

 usage. Existing knowledge as to conditions governing vitamin potency does not 

 warrant hard-and-fast control such as is now exercised to a degree on ordinary 

 commercial mill feeds. Without doubt, also, the United States Government 

 has a function in the matter, which may better be exercised than the authority 

 of individual states. Until such time as the Government takes over this function 

 and exercises it in an effective way, purchasers are at the mercy of unscrupulous 

 manufacturers and dealers. The principle involved should be that of the correct 

 labeling act, to the effect that whatever is claimed for the product sold should be 

 subject to check by a neutral state-supported agency. 



2. In the field of fertihzers and other products sold for the purpose of increasing 

 the productivity of the soil, there is now an array of inoculants which is giving 

 rise to serious thought as to effective use. These are classified in two groups: first, 

 so-called legume inoculants, the use of which is fairly well established, but which 

 in this State are sold without examination by any neutral agency to check state- 

 ment made; and general inoculants, the use of which is not yet well established. 

 While there have not yet been standard control methods worked out to govern 

 the sale of these products, yet the general application of a correct labeUng principle 

 will be fair to the manufacturer and give to our farmers and other users a degree 

 of protection which is sadly needed. 



3. A more elastic financial system is needed in the administration of the poultry 

 disease law. This activity is now practically self-supporting. It is impossible, 

 however, to foresee the need in any given year. Our budgets, of necessity, are 

 made out practically a year before they become effective. I therefore suggest 

 that in administering this law the Trustees ask for a sum materially greater than 

 now allowed — $14,000 or $15,000 — and arrive at an understanding whereby
