Blessing was the ship medic on the first Fram Expedition. The crew of the Fram was so healthy there was little doctoring to do during the three years. Datj pechatnuyu platu unch tda 7294.

Happily Blessing was also educated as a botanist. He started plant collecting as the Fram sailed along the Siberian coast and continued by collecting algae in the ice. In addition he doctored the expedition dogs.

Every month Blessing weighed and checked the expedition members. Unlike most other Arctic expeditions of the time, this crew blossomed and gained weight.

Fridtjof Nansen and Hjalmar Johansen left the Fram on the 26th of February 1895. They lashed their equipment to six dog sledges and would, of course, be completely self-reliant during the whole expedition.

No communication with the outside world or retreat was possible, and they would have no chance of finding the Fram again. The first attempt failed. The sledges were too heavy and the ice conditions too difficult so they turned back in order to reduce the equipment load. The sledges were improved and a new attempt was made but this also failed. Finally on the 14th of March they left the Fram at 84° 4' N in a temperature of -32 °C and turned their course northwards.

On the northern tip of Franz Josef Land they had to build a shelter for their winter quarters. They hacked away at the surface to make a hollow and then surround­ed this area with stone walls which they filled as best they could with moss. A long pine-log which had been washed ashore served as the ridge-piece, and over this they laid walrus skin.

In order to preserve warmth, they refashioned the woollen sleeping bag, so that both of them could creep into it. It was a long winter in the «den», as they called the stone-hut.

In the end, you were happy with the result, and you learned a lot of new skills. When a kit challenges you, you also learn what not to do. This happened to me a whole lot in this build.
