Goff, of Madison, Wis. These cards were 

 described by Dr. Jas. Fletcher, Dominion 

 Entomolog-ist and Naturalist, in his annual 

 report for 1898, and were found by him to 

 give good satisfaction. The cards are made 

 of a thinner grade than the ordinary tarred 

 paper, so that they will be more flexible, are 

 three inches in diameter, and are six-sided. 

 There is a slit from the circumference to the 

 centre, where there is a star-shaped cut. As 

 soon as the plants are set out the discs 

 should be put on. The slit to the centre 

 permits of slipping the card on the stem of 

 the plant, the star-like cut in the centre 

 making it fit very closely. After this is 

 done it is pressed flat upon the ground, the 

 surface of the latter having been previously 

 levelled, so that the fly can not crawl under 



to lay her eggs. As the insect will, as a 

 rule, not lay her eggs on the card, the plant 

 is practically safe if the disc is put on at the 

 proper time and in the right manner. If 

 the card does not fit tightly about the stem 

 of the plant there will be room for eggs to 

 be deposited. It is very important to put 

 on the discs when setting the plant, as the 

 eggs are usually laid immediately after the 

 plants are set. The photo showing a cauli- 

 flower plantation at the Central Experi- 

 mental Farm, on part of which the discs 

 were used, showing clearly the great .ad- 

 vantage of using them.

 Niemetz, for it gave him an opportunity of 

 comparing the fruits of Ontario with those 

 of his own country. 



Mr. Niemetz was for many years a 

 regular paid subscriber to this journal 

 and frequently contributed to its pages.

"Russian fruit growers have lost in Mr. 

 J. Niemetz one whose public addresses were 

 always received with close attention. He 

 was the second son of the eminent Bohem- 

 ian author, B. Niemetz, and he inherited 

 from his mother the highest qualities of 

 heart and mind. Left early an orphan, he 

 was unable to finish his course of study, and 

 supported himself by topographical drawing 

 at Prague, where his remarkable abilities in 

 this line were observed by some admirers of
