Then there is the knackbread in flat, round cakes, the common rye 

 bread of Sweden ; the want bread (noth brot) of Lapland, with the 

 ground reindeers' flesh, birch-bark, rye-straw, and barley-meal, from 

 which it is made. Also, the braudy distilled from reindeers' flesh — no 

 unimportant item of industry — is not wanting. Besides the narcotics, 

 as coftee, tea, &c., there is a glass containing a kilogram of wheat, 

 and near it similar glasses containing the starch, albumen, water, (Src, 

 the constituants of a similar quantity of wheat. 



This system of illustration is carried out with potatoes and other 

 foods, and their comparative value for nutrition is thus very forcibly 

 shown, a kilogram of potatoes, for example, cootaining 200 grains 

 starch, and 750 grains or two-thirds its weight of water, and on 

 another shelf we see the elements of straw compared with those of their 

 ])roper grains. 



Another case shows the various processes of starch-making, the 

 gluten being also utilized in the preparation of macaroni, &c., being- 

 added to the flour from Northern Europe, that is found very deficient 

 in gluten as compared with that grow^n in South Europe. All the varie- 

 ties of starch known in commerce are shown, and we obsi^rve that most 

 of the Sago starch of commerce is potato-starch, colored with, burnt 

 sugar or iron. 



Finally we have models of all parts of the floMers of cultivated plants, 

 models of barns and farmsteads, an excellent collection of fruits, the 

 herbarium, the cases of sugar and its manufacture, of flax in its difter- 

 ent forms and stages, paintings of cryptogamic plants, horseshoes and 

 methods of shoeing, bees and bee-hives, and all the miscellaneous arti- 

 cles necessary to complete the representation of agricultural industry 

 here presented. 



It is not intended to limit the influence of the museum to the mere 

 exhibition of its contents to visitors, but lectures are to be given, illus- 

 trated by its collections, which the students of the agricultural college 

 are expected to attend. Three days each week the museum is open to 

 the public, free, and special iiermission for study may be obtained by 

 students, on application. At the close of its first year the museum 

 (jomprised 17,000 specimens; it now possesses 27,00*0; most of which 

 have been obtained by donation. When a permanent building shall be 

 erected, it is the intention to have workshops included, suitable for the 

 preparation of models, &c., for which there is great need. The atten- 

 tion of the curator has hitherto been directed to arranging and classi- 

 fying the collection, with a view to ascertaining its deficiencies, that 

 they may receive especial attention, and it is proposed that the history 

 of improvement in the various utensils and ijrocesses shall be as com- 

 pletely illustrated as possible.

 whose farms are attacked for the first time, are asking for information 

 as to the best means for preventing their ravages, we deem it necessary 

 to republish what has been said in former reports regarding their natu-
