In outlining the floor plan of a creamery plenty of room should be al- 

 lowed but no more than can conveniently be utilized. The machinery 

 should be so placed as to avoid waste space and so that the factory may be 

 operated with the least possible amount of labor. It is poor policy to 

 economize on space where more, in reality, is needed. Two places where 

 such economy is often visible are the coal room and the supply room. The 

 coal room for most creameries should be large enough so it will hold a 

 carload of coal. The supply room for a creamery with from 600 to 1,000 

 cows should have a floor space of not less than 250 square feet and it 

 should be conveniently located and in a place where all dust is excluded. 

 It should furthermore be kept dry. The writer has in mind a creamery 

 which was recently built having a supply room 11 by 8 feet and in order 

 to save space there was only one door, and that was an outside door 

 leading to the room. Consequently the supplies had to be carried on the 

 outside of the building for about 25 feet. Another creamery was built 

 with a supply room of nearly the same size but with the entrance close 

 to the coal room. In this case many of the supplies are badly damaged 

 by coal dust. 



Creameries erected by the college during the past year have been 

 erected from cement blocks, bricks, hollow tile and hollow tile and brick. 

 In the latter case the outside wall consisted of four-inch brick, the inside 

 of four-inch hollow tile, leaving a two-inch air space between the two. 

 For inside partitions hollow tile was used and for roofing fire proof mate- 

 rial. A building thus constructed and of a size 30 by 60 feet can be built 

 for about $3,000. A building of the same size but constructed from ce- 

 ment blocks will cost about $2,000. A creamery of the size mentioned can 

 be built and equipped for about $4,500, but not less than $5,000 should be 

 subscribed in order that they may have sufficient left for working capital.
