More Dandelions, Less Spinach.--( Science, Vol. 80, p. 142. ) According to EMMETT BENNETT, in Contribution No. 192 of the Massachusetts Agricultural Experiment station, dandelions in the form of greens are a desirable item of diet. Analyses show the dandelion to have a high protein (15.76 per cent.) and a very low fiber (9.79 per cent.) content, accompanied by a high ash and to contain such minerals as calcium and phosphorus in abundance.

More interesting yet is the discovery that dandelions contain more calcium and phosphorus than does spinach. However, the latter beats out the former in m{ignesium content. Of all those examined, cabbage leaves had the highest calcium content and lettuce the lowest. Mangold ~ leaves are highest in magnesium. There seems to be no good reason why dandelions could not be culti- vated to the extent now enjoyed by spinach.
