Solstitial and Equinoctial Rains.—Our year, then, in respect of quantities of rain, exhibits a dry and a wet moiety. The latter again divides itself into two periods distinctly marked. The first period is that which connects itself with the popular opinion we have been discussing. It may be said on the whole, to set in with the decline of the diurnal mean temperature, the maximum of which, we may recollect, has been shown to follow the summer solstice at such an interval as to fall between the 12th and 25th of the month called July. Now the 15th of that month, or Swithin’s day in the old style, corresponds to the 26th in the new; so that common observation has long since settled the limits of the effect, without being sensible of its real causes. The operation of this cause being continued usually through great part of the eighth month, the rain of this month exceeds the mean by about as much as that of the ninth falls below it.
As regards St. Swithin and his day, it may be observed, that according to bishop Hall when Swithin died, he directed that “his body should not be laid within the church, but where the drops of rain might wet his grave; thinking that no vault was so good to cover his grave as that of heaven.” This is scarcely an exposition of the old saying, which, like other old sayings, still has its votaries. It is yet common on this day to say, “Ah! this is St. Swithin; I wonder whether it will rain?” An old lady who so far observed this festival, on one occasion when it was fair and sunshiny till the afternoon, predicted fair weather; but tea-time came, and—
“there follow’d some droppings of rain.”
This was quite enough. “Ah!” said she, “now we shall have rain every day for forty days;” nor would she be persuaded of the contrary. Forty days of our humid climate passed, and many, by their having been perfectly dry, falsified her prediction. “Nay, nay,” said she, “but there was wet in the night, depend upon it.” According to such persons St. Swithin cannot err.
It appears from the parish accounts of Kingston upon Thames, in 1508, that “any householder kepying a brode gate” was to pay to the parish priest’s “wages 3d.” with a halfpenny “to the paschall:” this was the great wax taper in the church; the halfpenny was towards its purchase and maintaining its light; also he was to give to St. Swithin a halfpenny. A holder of one tenement paid twopence to the priest’s wages, a halfpenny to the “paschall;” likewise St. Swithin a halfpenny.
Rain on St. Swithin’s day is noticed in some places by this old saying, “St. Swithin is christening the apples.”
