duce more prompt coming up but 1t is doubtful if the necessary work at tending such a job pays. It is cer- tainly not essential.
 Q. Would you advise setting out sweet potatoes this late? U. IT., Route l.
 4. 1t is rather late. If season Is favorable and with good cultivation some potatoes would be made but normal yields could not be expected.
 o. My verbenas are rusting, that ia. the leaves seem to turn yellow and parch up. What could I do for themY Miss L.
 A Dust the plants with powdered sulphur. Try to get as much under the foliage as possible. Repeat at week intervals until disease disap- pears.
 0. Did you ever hear of the leaves of black walnut and the hulls being good for plant lice? How do you make use of them7 Mrs. D., Attalla.
 A. Those are among the first rem edies ever used against insects. The leaves or walnut hulls were steeped in water to extract the juices but no definite standard of strengths were IT aintained. Such decoction is very offensive to most insects, and due to certain tannins, will actually kill many soft bodied insects by contract- ing the body tissues. A little soap in such decoctions Is said to render the treatment more effective.
 Q. I see directions about paint ing trees with carbonate of lead. What Is this and how is it prepared? C. S., Albany.
 A. Carbonate of lead Is simply white lead that you buy at paint stores. You add enough linseed oil to make 1t thin enough to spread like house paint.
 c. l have been told that the refugee bean is the best for fall crop. Would you advise Its use against others? c. F., Evergreen.
 A. It is hardy, very prolific and a good shipper, but 1t gets tough and stringy quicker than such sorts as giant stringless. It is largely used for fall crop.
 O. How long will it take Mexican June corn to make roasting ears after planting? l.. S., Anniston.
 A. A great deal depends on the type of the Mexican June corn plant ed. Some dwarf types will make roasting ears. under favorable con ditions. in 65 to 70 days. Some later and tall types require 80 to 90 days. Much also depends on culture and moisture.
 e. notice in a flower maga- zine that copperas water is good application to keep plants free of disease. How Is 1t made? Mrs. E. D. Edgewood.
 A. This Is fair sample of much information you read, worthless. be- cause impractical to make use of.
 
 pound of copperas in two gallons ot water, then add. half pound of slaked or hydrated lime. This woul answer for hardy foliage, but on soft or tender foliage, the amount of copperas should be reduced by half.
 Q. There is dark. k.green worm with black spots on his back and Nyelfow head. that is eating a privet hedge. Give treatment to destroy? M. P, R, F. D. g.
 A. Kerosene oil emulsion diluted to the proper strength will kill. An other effective. tablespoonful arse nat of lead to the gallon water and spray thoroughly.
 c. l read an interesting article about killing insects with hot water. but it did not say how hot the water should be. Could you give me any idea about this? R. D.. R. F. D. ?.
 A. Hot water is very effective destroyer of many insects and par ticularly earth worms slugs, grubs, plant lice and in fact all soft bodied insects. The difficulty with it's use Is knowing just how resistent to heat the different plants are. The same plant at different stages of growth withstands various degrees of heat. Another trouble. if the hot water Is sprayed on, 1t coois so rapidly that You cannot control it. Many insects cannot survive hot water at 120 to 130 degrees of heat and most plants will stand such water without injury. Some will actually stand water heated to 200 degrees, almost boiling. One would be compelled to experiment before taking any chances on a lot of plants.
 Q. Will black eye peas mature If I get them in by July 10? S. r., Pelham.
 A. Any ordinary variety of COW peas will mature planted in July and many will mature planted as late as August.
