thanks Linnaeus for his letter of the 8 October 1771 [this letter has not come down to us]. He reports that during the summer he had visited Vadstena in order to see bees collecting from Fumaria bulbosa, where it grows abundantly. Hagström comments that it was curious that any bee appreciates Fumaria bulbosa when they also refuse to visit Fumariam officinalem, which grows like a weed in the gardens of Linköping. Hagström continues to tell Linnaeus his observations on various plants and their degrees of attraction to bees.

Hagström sends Linnaeus a drawing he has copied from Johann Leonhard FrischFrisch, Johann Leonhard

had published the clearest drawing.

Hagström has sent observations on the Siskin to the Inrikes Tidningar. The hen lays 4-5 eggs in each clutch, with four clutches each summer, when she is allowed to mate freely and build in the room in which she had been kept for a couple of years, flying in and out of a window kept slightly open. She had no access to clay but had built her nest out of fine blades of grass and grass panicles, building a new nest for each clutch. When the young are about 3-4 days old she mated again with a new admirer, to whom she is admitted in his cage.
