sends his and his friends’ observations [Vernatio arborumLinnaeus, Carl Vernatio

(Uppsala [1753]). Soulsby no. 1739.
] made during sowing and harvest in several places in the local area. Information about Halland, however, is still missing.

He further states that despite the fact that it is hard to believe that the fish Salmo alpinus L. could possibly be found so far from Lapponian lakes, one single location of the species mentioned - Nötsjön - has been detected in Bollebygd’s jurisdictional district in the province of Elfsborg. There this species will appear once a year at spawning-time. Ahlelöf’s observation was founded on one dried sample but he promises to examine a fresh fish next season.

Ahlelöf adds that should he be given the opportunity to append a new fish to Natural History, he would regard it as a very special privilege. Consequently he will send - as soon as possible - a sample of the said fish to be critically examined and scrutinised by Linnaeus. Ahlelöf encloses his own description for Linnaeus’s rectification. Whether the fish belongs to Sciaena or Perca is doubtful. However, Ahlelöf assumes it to be Perca.

Ahlelöf also mentions that the local farmers have noticed that if ice of lakes and streams in springtime is left to melt on the shores, they can be certain of a rich harvest. If the snow and ice, however, is allowed to melt in the water a poor harvest is to be expected. This phenomenon has been observed several times. Ahlelöf makes a reflection on the connection between water flow and harvest quality, as found in Egypt.

The letter ends with information about the initiation of a position as senior master in Natural History at the local secondary school. Lars MontinMontin, Lars (1723-1785).
