Near the ferry at Tornea I picked up the Fresh-water Sponge, _Spongia lacustris_ of Newton, (_S. lacustris_; _Syst. Nat. v._ 1. 1299. Linnæus here refers to Mr. Newton, the friend of Ray, who found the Sponge in question in the Norwich river, where it still exists. It is however denominated in Ray's _Synopsis_, _S. ramosa fluviatilis_, not _lacustris_. Linnæus quoted from memory.) _August 16._ In dissecting the flower of _Artemisia_ (_vulgaris_), I was struck with its very curious conformation. (This alludes to the want of a limb to the corolla of the female or marginal florets. See _Fl. Lapp. ed._ 2. 244.) _August 17._ I went by sea from Tornea to Calix. The wind proved contrary. The islands abounded with Whortle-berries, and with the fruit of _Rubus saxatilis_. On one called Korsholm I met with a sort of _Behen_. Can it be the same with that which grows in cornfields? Their different parts are tolerably alike. This grew among the pebbles of the beach. Its calyx is oblong. Leaves narrow. Stem erect. Fruit of one cell. In other respects it resembles _Behen_. (This was _Cucubalus_ (_Behen_) variety the third, or γ, _Fl. Lapp. n._ 180. _ed._ 2. 149. _Silene maritima_, _Fl. Brit._ 468. _Engl. Bot. t._ 957. We have found it remain for many years unchanged in a garden, propagating itself by seed, though Linnæus reports that the third year he could not distinguish his from our common _Silene inflata_, his _Cucubalus Behen_.) ŒCONOMICAL REMARKS CONCERNING THE NEIGHBOURHOOD OF TORNEA. The soil is various, sometimes clay, sometimes sand. The corn-fields are sown every other year, and lie fallow the intermediate seasons, half of each field lying fallow, while the other half is cultivated. The former is ploughed during the whole summer, to prevent the growth of grass or weeds, which might exhaust it. Barley is sown in these open fields only. Rye is cultivated on land that has recently been cleared of its wood by burning, but not in any great quantities. Turnips and Rye are sown together in one crop, and not, as usual in other places, Turnips one year and Rye the other. Rye bread is reserved to treat visitors. Barley bread is of three different qualities; 1. made of the unmixed barley; 2. of a mixture of barley and chaff; 3. of chaff without any addition, except now and then a handfull or two of barley. This last is their _Spis-bröd_, or household-bread. The plough is of the same construction as that used in Westbothland.
