Thus, for instance, according to a Basque proverb, "A wet May, a fruitful year," whereas it is said in Corsica, "A rainy May brings little barley and no wheat." Instances of this kind are of frequent occurrence, and of course are in many cases explained by the difference of climate.

But in comparing all branches of folk-lore, similar variations, as we have already observed, are noticeable, to account for which is often a task full of difficulty.
Of the numerous other instances of weather-lore associated with agricultural operations, it is said in relation to rain:-- "Sow beans in the mud, and they'll grow like wood." And a saying in East Anglia is to this effect:-- "Sow in the slop (or sop), heavy at top." A further admonition advises the farmer to "Sow wheat in dirt, and rye in dust;" While, according to a piece of folk-lore current in East Anglia, "Wheat well-sown is half-grown." The Scotch have a proverb warning the farmer against premature sowing:-- "Nae hurry wi' your corns, Nae hurry wi' your harrows; Snaw lies ahint the dyke, Mair may come and fill the furrows." And according to another old adage we are told how:-- "When the aspen leaves are no bigger than your nail, Is the time to look out for truff and peel."[7] In short, it will be found that most of our counties have their items of weather-lore; many of which, whilst varying in some respect, are evidently modifications of one and the same belief.

In many cases, too, it must be admitted that this species of weather-wisdom is not based altogether on idle fancy, but in accordance with recognised habits of plants under certain conditions of weather.

Indeed, it has been pointed out that so sensitive are various flowers to any change in the temperature or the amount of light, that it has been noticed that there is as much as one hour's difference between the time when the same flower opens at Paris and Upsala.

It is, too, a familiar fact to students of vegetable physiology that the leaves of _Porleria hygrometrica_ fold down or rise up in accordance with the state of the atmosphere.
