34 TURNIP. 



to seven inches wide, to the end of which I attached the small wheels 

 of a three-furrow drill, and put some handles to it to push it along 

 like a seed-barrow ; some bagging was nailed on the flat board to be 

 just above the ground ; this was kept well-tarred, and, as it is pushed 

 in front over the rows of young plants at a brisk pace, the fly, 

 in jumping from the plant, comes in contact with the tarred bagging, 

 and sticks there. Thousands may thus be soon caught, and a man 

 can go over five or six acres twice in a day. (C. C.) 



A short note mentions fly being caught by wheeling a board 

 to cover two rows painted with treacle or any sticky substance which 

 the fly would adhere to, and thus be got rid of. (F. W.) 



The following plan, similar in principle to those above mentioned, 

 but worked on a much larger scale, has been contributed, as mentioned 

 by Prof. Allrnan to have succeeded : 



A large board, say the size of a dining-table, should be placed on 

 wheels high enough just to clear the top of the Turnip drills. The 

 under side of this board is to be covered with tar (pitch), and then 

 dragged by horses over the field. The beetles naturally spring up 

 and are caught in the tar. (Communicated by E. S. S.) 



The following observations show success to plants on well-cultivated land, with 

 guano applied by means of the water-cart in dry weather ; mention also 

 is made of sea-weed as a manure. 



From Lake Carra, near Killarney. Here, on a gravel (red sand- 

 stone) and peat soil, there are good Turnips with no " fly" either in 

 Swedes or Aberdeens. These were on deep-ploughed ridges, on 

 Potato-ridges of 1880, prepared by spade-labour ; these 1880 beds 

 put on the furrow of similar ridges of 1879, thus getting out stones to 

 make way for its first ploughing in 1881. These were partly 

 manured with well-rotted farm manure, cow-manure on furze bedding, 

 partly with red sea- wrack (the kind used for " kelp," locally known as 

 red- weed), and two bags of guano were watered, by means of the 

 water-cart, on to the young Turnips in dry weather, which took root 

 quickly and throve. Food-plants of fly were absent, the surroundings 

 being mainly bogs, heath, trees, and Potato patches, and no wild 

 Mustard. (J. B. K.) 



I have noticed beautiful fields of Turnips, where, in rotation with 

 other crops, seaweed has been used. (J. S.)
