board, which has been sized and pressed. It is fastened to the studs 

 with broad-headed tacks, and dampened a little, so that shrinking will 

 make a tight fit. The strips are put on across the studs in the same 

 direction as lath, and the wall paper is pasted over the pasteboard in 

 the usual way. In mild climates it has been used for the outside of 

 houses, but the paper for this purpose is manilla board, very tough and 

 quite thick. It is not better or more durable than wood and plaster, 

 but it is a great deal cheaper ; and summer bed-rooms, kitchens, wood 

 and coal sheds, hen-houses, and the pioneer cabin, can be made of it. 



Dr. J. V. C. Smith — I am surprised to hear Professor Colton con- 

 demn paper as a building material. He surely cannot have investi- 

 gated the subject. Why, sir, they make buckets, tubs and water- 

 pipes from it, and in Germany I have seen handsome cottages and 

 churches built from paper. 



Prof. Colton — I have investigated it, and that is just why, in my 

 practical view, I do not believe it will be of any great value. It is 

 nearly as costly as sheet-iron, and not so strong. Some fancy men 

 may build a villa out of it, but it would be rather a costly material in 

 this country. There is, however, much to be learned about the 

 uses of paper, and there is a wide field yet to be opened to the straw 

 paper business. 



No Advantage in Shallow Milk Pans. 

 Mr. E. Meeker, Olympia, W. T. — The absence of ice, or at best, 

 irregularity of supply, makes it' necessary to look to other plans for 

 equalizing the temperature of milk. Where there is spring-water or 

 well-water of a low temperature, the temperature can be regulated 

 by setting the pans or cans in water. I have adopted the plan of 

 using cans eight inches in diameter, and twenty-eight in height. 

 These held approximately thirty-three pounds of milk, and making 

 about one pound and a half of butter to the can. With well-water 

 at fifty and fifty-three degrees in summer, we have but little difficulty 

 in keeping the temperature down to sixty-three degrees, by adding a 

 few bucketfuls of water at times. Experiments have shown that 

 twenty-two pounds of milk were required to make a pound of butter, 

 where cans were used. Where pans were in use the result varied so 

 much that we could arrive at no definite conclusion, sometimes 

 yielding one pound of butter to twenty and one-half pounds of milk, 

 at other times requiring twenty-four to twenty-five. As we had no 

 place to give the pans a fair test, the experiment proved incomplete. 

 As to quality, we think there is no doubt, as exposing less surface to
