TURNIP FLY.

Note. Page 66, line 14, "an im- 

 plement called a K." The name is 

 " Koldmoos Weed Eradicator"; it is 

 described as a horizontal drum re- 

 volving at high speed between two 

 carrying wheels ; the drum being fur- 

 nished with rows of combs protruded 

 and withdrawn by machinery, whereby 

 the weeds entangled amongst the 

 teeth are either pulled up or the 

 flowering heads torn away. ED. 



and on these plots there was no fly-attack, although in the case of 

 plot 3, sown on June 21st (when it will be seen there had been good 

 rainfall for some time), the ground was in anything but good condition 

 for roots on account of its working rough. 



The second sowing of plot 4, which was re-drilled on June llth, 

 came into the period at which others throve, and was "partly eaten"; 

 but, looking at the bad amount of fly previously present on the ground, 

 this partial destruction seems likely 

 enough; and also, in this case, 

 sowing and re-sowing took place, 

 respectively, on May 19th and June 

 llth, so that there was not as good 

 an interval between as in the satis- 

 factory re- sowing of plot 5. In this 

 case the first sowing, which was 

 destroyed, took place on May 25th 

 and 26th, and the second, which was 

 not attacked on June 23rd, 24th, 

 and 27th, thus being put in after a 

 longer space of time, including in it 

 rainfalls of more than a quarter of an 

 inch on several days.
