Cimex lacustris, a kind of Water-bugs, [[127]]hopped in numbers on the surface of waters which had a slow course.
Dytiscus piceus, or, the great Water-beetle, swam sometimes in the water.
About sixty years ago, the greatest part of this country was covered with tall and thick trees, and the swamps were full of water. But it has undergone so great a change, as few other places have undergone, in so short a time. At present the forests are cut down in most places, the swamps drained by ditches, the country cultivated, and changed into corn-fields, meadows, and pastures. Therefore, it seems very reasonable to suppose, that so sudden a change has likewise had some effect upon the weather. I was therefore desirous of hearing from the old Swedes, who have lived the longest in this country, and have been inhabitants of this place during the whole time of the change mentioned, whether the present state of the weather was in some particulars remarkably different from that which they felt in their younger years? The following is an account which they all unanimously gave me in answer to this question.
The winter came sooner formerly than it does now. Mr. Isaac Norris, a wealthy merchant, who has a considerable share in [[128]]the government of Pensylvania, confirmed this by a particular account. His father, one of the first English merchants in this country, observed, that in his younger years, the river Delaware was commonly covered with ice, about the middle of November, old style, so that the merchants were obliged to bring down their ships in great haste before that time, for fear of their being obliged to ly all winter. On the contrary, this river seldom freezes over at present, before the middle of December, old stile.
It snowed much more in winter, formerly, than it does now; but the weather in general was likewise more constant and uniform; and when the cold set in, it continued to the end of February, or till March, old style, when it commonly began to grow warm. At present, it is warm, even the very next day after a severe cold; and sometimes the weather changes several times a day.
Most of the old people here were of opinion, that spring came much later at present, than formerly, and that it was now much colder in the latter end of February, and the whole month of May, than when they were young. Formerly [[129]]the fields were as green, and the air as warm, towards the end of February, as it is now in March, or in the beginning of April, old stile. The Swedes at that time made use of this phrase: Pask bitida, Pask sent, altid Gras, that is, we have always grass at Easter, whether it be soon or late in the year. But perhaps we can account as follows, for the opinion which the people here have, that vegetation appeared formerly more forward than it does now. Formerly the cattle were not so numerous as now; however, the woods were full of grass and herbs, which, according to the testimony of all the old people here, grew to the height of a man. At present a great part of the annual grasses and plants have been entirely extirpated by the continual grazing of numbers of cattle. These annual grasses were probably green very early in spring, and (being extirpated) might lead the people to believe, that every thing came on sooner formerly, than it does at present.
It used to rain more abundantly than it does now, during the harvest especially, the rains fell in such plenty, that it was very difficult to bring home the hay and corn. Some of the last years had been extremely dry. However, a few people were [[130]]of opinion that it rained as plentifully at present, as formerly.
All the people agreed, that the weather was not by far so inconstant, when they were young, as it is now. For at present it happens at all times of the year, that when a day has been warm, the next is very cold, and vice versa. It frequently happens that the weather alters several times in one day; so that when it has been a pretty warm morning, the wind blows from N. W. about ten o’clock, and brings a cold air with it; yet a little after noon it may be warm again. My meteorological observations sufficiently confirm the reality of these sudden changes of weather, which are said to cause in a great measure the people to be more unhealthy at present, than they were formerly.
I likewise found every body agree in asserting, that the winter, betwixt the autumn of the year 1697, and the spring of the year 1698, was the coldest and the severest which they had ever felt.
April the 6th. Sanguinaria Canadensis, which is here called Blood-root, because the root is great and red, and, when cut, looks like the root of red beet, and the Epigæa repens, which some call the creeping ground Laurel, were both beginning to [[131]]flower. The former grew in a rich mould, the other in a poorer soil.
