Storch H. At the Hive Entrance

B-I040 BRUSSEL, I, rue de l'Escadron, 1985. — 70 p.
When preparing this first edition, we asked Dr. DREHER, who collaborated with Prof. STORCH, to
revise the text, paying particular attention to the latest developments in the field of bees disease, and we want to thank him warmly for this.
We have also thought it useful to complete the observations made at the hive entrance and on the bottom board cover, with those interesting observations that one can make at the building frame and which we have taken from the book» Der Baurahmen « written by the inventor and promotor M.E. PASCHKE.
So it is that we can present our readers with a set of observations, all of which can be made by the beekeeper without him having to open or work within the colony.
All these observations are very interesting, but only useful if they are understood and correctly interpreted.
This is the aim of this work.
