The Question Box. 107 



Question. — How many cubic feet of air does a cow require in 

 the stable? 



Mr. Smith. — I don't know exactly; but I think about 500 feet. 



Mr. Lillie. — It would depend very much on the ventilation of 

 the stable. The air should be pure and the stable free of odors. 

 There should also be plenty of sunlight present. 



Question. — Can any one get a sample of any foods he may 

 have, analyzed at the experiment station ? If so, will he get a 

 report of the same? 



Mr. Smith. — ISTo ; if the station should attempt to analyze all 

 the stun' sent to it, no time would be had for anything else. Be- 

 sides, there would not be chemists enough. But, if you can get 

 a good, fair, even sample of a suspicious food — one that there 

 is no record of at the station — the director will make a careful 

 microscopical examination of it, and, if he thinks best, will order 

 a chemical analysis; not otherwise. If it should be analyzed the 

 sender will receive a report. 



Question. — Does a broad-tired wagon draw harder than a nar- 

 row-tired one ? What width wheel is best for all farm work ? 



Dr. Smead. — For hauling loads over meadow or pasture ground, 

 the wide tires are preferable; but, with hard, dry roads, I should 

 prefer the narrow tire. 



A Farmer. — We can draw 10 or 15 bushels more potatoes out 

 of the field on a wide-tired wagon than on a narrow-tired one. 



Mr. Smith. — Wide tires do not cut up the roads in a muddy 

 time as do narrow ones; and if every wagon used on the road were 

 wide-tired, the roads would be much better than they usually are. 



Question. — What is the best way to get rid of quack grass ? 



Mr. Rice. — I had a piece of it. I summer fallowed the ground 

 and sowed wheat. When the wheat came up I could not find a 

 spear of quack. Plow the land early, but shallow; then run a cut- 

 away harrow over it every few days. In other words, prevent 

 the quack from growing; don't allow it to breathe. In this way 

 one may subdue a piece of quack enough so that a crop of buck- 

 wheat or peas may be raised the same season, while the quack will 

 have been killed out. In the fall sow wheat, and seed in the 

 spring. 



Question. — How shall we eradicate wild carrot? 



Mr. Smith. — It is more difficult to destroy than is quack. Once 

 it gets into the land, unless the land can be plowed and cultivated, 

 there is no way by which it can be eradicated, as it seeds heavily 

 and the seeds live a long time. Where a rotation of crops can
