In reply to R. L. B., page 110, April No. Gardener's Monthly, would say we prefer to use skimmed milk, made of the proper consistency by stirring into it powdered whiting. If skimmed milk is not so easily obtained as buttermilk, I use the latter. If a good shading be required, make thicker and put on with brush. For pits,' frames etc. when a light shading is necessary, make sufficiently thin to throw it on with a syringe. All things considered the above is the best we have yet discovered for use as a temporary shading, but for something more permanent good white lead paint daubed on with a brush through a cloth is the only satisfactory way we have yet found.
