firming and showing the method of action of one of the ac- 

 cepted methods of lessening the ravage of Daddy Longiegs 

 grubs. 



Hand-hoeing and horse-hoeing are noted as remedies, the 

 former being preferable, as it disturbs the working of the 

 grub, and hills some, whilst it exposes others to the birds ; at 

 the same time this is " a dear remedy for a bad attack," as the 

 grubs lie so close in amongst the roots of the plants. In a 

 bad attack on a twenty-acre field of Peas, the outlay was at 

 the rate of 4s. to 5s. 6d. per acre for five hoeings. — (E. A. F.) 



The following applications have been found uscfid in cases of 

 had " LcatJicr-jacket " grub presence : — 



In a case of very severe attack on a twenty-acre field of 

 Oats belonging to Mr. D. Byrd, of Tarporley, Cheshire, a 

 mixture was applied at the rate per acre of guano \^ cwt. ; 

 kainite 1 cwt. ; superphosphate 1 cwt. ; and salt 2 cwt. This 

 was applied about the 10th of May, the harrows followed the 

 manure drill twice, and a heavy Cambridge roller was taken 

 two or three times over the whole field at the time. "When 

 this was given it was estimated that fully half the crop was 

 taken by the grub ; but the application brought the field 

 round so, that at last the crop was estimated to be forty to 

 forty-five bushels the acre ; in Mr. Byrd's words, " the crop 

 restored, minus the cost of manure." 



Guano has answered as a dressing, and guano and salt 

 mixed applied at the rate of four hundredweight per acre, in 

 the case of a very bad attack of grub on Oats, after Clover, 

 was found perfectly successful in checking attack and running 

 on a good growth, resulting in a fine crop, when all other 

 means to stop the ravage had failed. — (S. F.) 



With regard to the action of salt : probably it does some 

 good by driving the grub down ; but, as an application by it- 

 self, it has failed in many cases. As a dressing at the rate 

 of seven hundredweight per acre to a grub-run field of twenty 

 acres, it did no good. — (J. H. W.) 



Special experiment, by applying salt on three occasions to a 

 number of Cabbages, planted in pots and healthy, before the 

 grub was introduced, showed that even with a quantity that 

 killed the plants, the grubs were to be found at increased 

 depths below the surface, these depths apparently regulated 

 by the amount applied ; but the grubs were in no way the 

 worse. 



It was found that the grubs might be immersed in strong 

 brine for twenty-four hours without being killed. — (11. S.)- In- 

 other experiments conducted by Mr. Kalph Lowe, previously 

 quoted, " brine was tried at a strength of one pound of salt to 

 a quart of water, and the grubs dropped into it died in a short
