"M. Regnard has been inquiring into the much-disputed problem, why vegetation does not grow well beneath trees, notwith standing that there is plenty of light, pure air, humidity, and warmth. He has confirmed the observations of M. Paul Bert, who had already shown that green light hinders the development of plants. Plants enclosed in a green glass frame wither and die as though they were in darkness. M. Regnard finds that plants specially require the red rays. If the sunlight is deprived of the red rays the plants soon cease to thrive. This fact explains why plants grow well in rooms upholstered or papered in red, while they wither in rooms upholstered or papered in green".

It can hardly be said that it has been a much-disputed point by English gardeners, at least, why vegetation does not grow well beneath trees. It has generally been supposed that the reason was the same as that which prevented plants thriving in a dark cupboard with the door shut. It was not known before that plants died in a green glass frame, but the contrary was supposed to be the case; and gardeners, even of Kew, if we remember correctly, painted some of their glass roofs green, and recommended the plan. The French horticulturists themselves shade their plant-houses with a kind of green Venetian blinds that gives everything inside a green look; and yet their plants thrive admirably. The "fact" of plants growing in red-papered rooms, and dying in green-papered ones, is unadulterated lunacy. As barren a piece of ground as we ever saw was under the branches of a spreading purple or red beech. It is the fault of French horticulturists and botanists that they are a trifle too "scientific" and philosophical. Their " high-class" gardening partakes too much of the laboratory, hence these errors and contrarieties.

It is not long since one of the most learned horticulturists in France, Lavallee, was at great pains to explain how it was that vegetation throve under beech and other trees; now we are having it explained by another of his countrymen why it does not thrive. It is this same "scientific" penchant which has created the innumerable fantastic systems of training fruittrees which finds favour with a certain section of French gardeners. There is not one fantastic shape but which is founded on some wise principle or other, but which nobody believes in but themselves - not even real French fruit-growers. If all the fine-trained trees in France were burned to-morrow, it would not make the smallest difference to the future supplies of the Halles Centrales. If you want to see fine examples of training, you have to seek them out like needles in a bundle of hay; but in a single journey from Dieppe through Normandy, '• which produces the best farmers and best gardeners in France," you will see how the fruit is grown, or where it comes from. It is like a long railway journey through orchards and gardens.

The vineyards at Thomery, Asparagus farms at Argenteuil, and the market-gardens round Paris, are old-fashioned institutions that have been carried on with marvellous success for generations, by old-fashioned common-sense people, who have nearly as much "science" about them as the ordinary farmer in this country has, but more method and industry.

Some of our great seed-firms seem to be going in for the "Hollo-way Pill" and "New Blood Restorer" method of advertising their Potatoes and other things. An advertisement like the following would hardly be admitted into the gardening papers, but it has for some time being going the round of the second-rate provincial prints, week by week, in the " promiscuous paragraph " style. We suppress names : -
