 Q. I am reserving land for a winter grain pasture. Which is the best rye. barley or winter turf oats? H., West Blocton.
 A. The rye is very satisfactory but a slow grower and must be planted early to prove profitable. Barley on good land is a much faster grower and more relished by live stock. Turf oats is a faster grower than either and very profi- table if land is fertile. A mixture of two or three would be my prefer ence.
 @. Where can I get information about how long it takes tree seed 10 come up after planting? c. A. Florence.

 IA This potato beetle is called the tortoise beetle and golden bug. It eats but little although it's larvae may cause serious injury earlier in the season. The beetles do not lay eggs this late, as a rule, and inas- much as the vines will now grow rapidly, not much danger could exist from this source If worms ap- pear, an arsenic spray is the treat ment.

Spraying With bordeaux will check the trouble One ounce of acitate of copper to three gallons of water is used with splendid effect. In the fall 1t would be good idea to remove all leaves. gather up and burn. Spray and re- peat in early spring.
