remedies and preventives. 27 



Carbolic Acid for the Cabbage Worm. 



As cheaper than pyrethrum powder and more quickly applied, the 

 following application may be made: One tablespoonful of the cheapest 

 black carbolic acid diluted in one gallon of water, applied sparingly, 

 after heavy rains, at intervals of three or four weeks, if the caterpillars 

 are observed. Persons who have tested the above, claim that it has 

 given them uninjured crops of cabbage, {Country Gentleman.) 



Road Dust for the Cabbage Worm. 



A simple and costless palliative, if not a preventive of the ravages of 

 this insect, has been found in the frequent use of dry dust. A quantity 

 of road dust should be kept in a covered vessel near the cabbage patch in 

 the garden, and every few days or after rains, a little of it should be 

 sifted over each cabbage head. 



Coal-oil Refuse for the Canker Worm. 



Instead of the tar or printers' ink band, applied about the trunks of 

 trees to prevent the ascent of the wingless Anisopteryx vernata, the re- 

 siduum from kerosene oil works may be used. It is cheaper and will 

 last twice as long as the tar or ink, not requiring renewal oftener than 

 once in six days. It has been used with success when printers' ink has 

 failed. ( Transactions of the Massachusetts Horticultural Society for 

 1883, Part I, p. 16.) 



A Wash for the Apple-tree Borer. 



The best protection from the injuries of the flat-headed apple-tree 

 borer, Chrysobothris femorata Lee, so far as known at the present, is 

 a wash made of soft soap and carbolic acid. Soft soap and lime, with 

 a little glue dissolved to promote adherence, is also used. As this insect, 

 unlike the round-headed borer, Saperda Candida Fabr., formerly known 

 as Saperda bivittata Say, does not confine its attack to the base of the 

 tree, but extends into the branches, and even into the terminal twigs, 

 as I have observed when the tree has become diseased, it is important 

 that the soap be applied to such portions of the branches as can be 

 reached. This coating, made in May, and again in early July and late 

 August, will usually prevent the deposit of the eggs; but it is not well 

 to trust alone to its efficacy. Where the insect abounds, the trees 

 should be carefully examined for the presence of the borer, which may 

 be detected by the excrementa or borings at the commencement of the 

 burrow, or, when the borer has just entered, by an exuding drop of sap 

 upon the bark at its place of entrance. A gentleman who has had
