If clotliing should become infected it could be put into a close box and 

 drenched with gasoline. As soon as the insects were killed the clothing 

 could be aired, when the odorous liquid would quickly escape. Bisulphide 

 of carbon could be used in the same way. This is deadly to all insect life ; 

 but it is fully as explosive and dangerous when fired as is gasoline. So if it 

 is used we cannot be too cautious.

No. 18.— FARM DEPARTMENT. 

 WHEAT.— NOTES ON VARIETIES GROWN ON COLLEGE FARM, '85 AND '8<3. 



This bulletin is issued to give- such facts in regard to the yield, hardiness, 

 and habits of growth of several varieties of wheat which have been grown 

 on the College farm the present season, as may be of general interest to the 

 wheat growers of our State. 



Field No. 8 in the regular rotation was sown with four varieties of wheat. 



Clawson. 



Eight acres of Clawson, Seed sown, 13^ bu. Sown Sept. 18, cut July 15. 

 Yield, 151| bu., 18f bu. per acre. 



The soil of this field is mainly a rather stiff clay loam; but a portion of 

 the field where the Clawson was sown was a reclaimed tamarack swamp. 

 The wheat on this portion of the field (a mucky soil) seemed to be very 

 much more injured by the droutli than on the heavier land. It produced a 

 heavy growth of straw which lodged badly, and gave a shrunken, poor qual- 

 ity of grain. The fly did serious damage to this variety; the others being 

 little affected. 



Rogers' Amber. 



Nine bushels of this variety were sown on six acres next to the Clawson. 

 Sown Sept. 19, harvested July 14. Yield, 159 bu., 26^ bii. per acre. 



This variety has stiff straw of medium length, stands up well, is hardy 

 and has given good satisfaction wherever it was sown last season as far as I 

 have been able to leaim. 



We have grown it two years; obtaining our seed from Hon. Henry Cham- 

 berlain, of Three Oaks, who introduced it in 1883, I believe, from Pennsyl- 

 vania. 



YIELD PROM DIFFEREKT AMOUNTS OF SEED. 



Martin's Amber. 



The next four acres were sown to this variety, with different amounts of 

 seed to each measured acre. 



The four plats were sown the 20th of Sept., harvested July 13th. 



First acre, 45 lbs. (f bu.) of seed. Yield, 21 bu. 

 Second acre, 60 lbs. (1 bu.) seed. Yield, 24-2 bu.
