same. As a result the standards of cleanliness and methods of work have 

 greatly improved, and has also the products of the creameries and cheese 

 factories of this state. 



(0) Weights and Measures. 



(4) Agricultural Statistics. 



(5) Labor. This division offers great opportunity in elevating the 

 labor situation on the farms and at the same time securing labor for 

 those who have drifted from the farm to the city, and who wish to return 

 to their early field of activity. 



(6) Veterinary and Live Stock Sanitary Work. 



(7) Entomology (including Orchards, Nursery, Fungicide and Insec- 

 ticide Inspection). 



(8) Apiary Inspection. 



(9) Stallion Registration. 



(10) Seed Inspection. 



(11) Pathological Inspection. 



(12) The Fairs. 



(13) Farmers' Institutes. 



The latter two do not come strictly under control work. Nevertheless, 

 there is some reason for including these under the departments of agri- 

 culture. The state fair work has always been under boards of agricul- 

 ture and is moreover too large an activity to be included under the educa- 

 tional work conducted by the state college of agriculture. There may be 

 less justification for including the farmers' institute; however, the control 

 work should be enforced in connection with educational work throughout 

 the state in acquainting the people with the laws and regulations, their 

 needs and advantages. In such w'ork the farmers institute would be of 

 great value. However, it is most likely that the farmers institute should 

 give opportunity for the state departments to handle their educational 

 control work as well as to carry forward the extension work of the 

 college of agriculture under some co-operative arrangement. 



IMPORTANCE OF CONTEOL VN'ORK. 



There is no part of the activities of the state in behalf of agriculture 

 more important and evolving greater financial responsibilities and advan- 

 tages than the control work. A few examples will illustrate: 



(1) Nursery and Orchard Inspection. In this work we encounter the 

 San Jose scale. This disease was introduced from China and possibly 

 elsewhere, the average cost to the eastern states of controlling this 

 disease runs very close to ten million dollars a year. We also meet the 

 gypsy and brown tail moth. This insect was introduced into one of the 

 eastern states for experimental purposes for the purpose of improving 

 the race of silk worms by cross-breeding. Accidentally a glass containing 

 these worms was spilled out of the window, immediate action was taken 

 to locate and destroy all of the insects that escaped, but a few remained 

 and as a result a disease of fruit trees was started in the east which 

 costs the state of Massachusetts one million dollars annually for its con- 

 trol. Every city in the west, as well as in the east, has had ample evidence 

 of the losses due to the cotton maple scale in the loss of splendid shade
