Experimcnls in the apiary (pp. 07-103). — " According to the phins 

 adopted two years ago, the experiments iu the apiary are along four 

 lines: testing honey plants to determine whether any will pay for 

 planting and growing exclusively for honey ; breeding bees by crossing, 

 in hopes to secure a superior race ; analyzing various kinds of honey 

 to ascertain if any test for honey is possible and can be relied upon ; 

 and various points in manipulation, etc." 



iTotes are given on experiments with the Koclcy Mountain bee plant 

 {Cleome inteyri/olia), GhniMnun honey i)hint {EcJiinops sphccroce2)]iala.s), a 

 species of Melissa, and Japanese buckwheat. A lateraccouut of similar 

 experiments is given in Bulletin "fTo. G5 of the station (See Experiment 

 Station Kecord, Vol. II, page 279). The cross-breeding of Syrian and 

 Caruiolan bees has given promising results. Collections of honey 

 stored rapidly and slowly are being made, with a view to testing the 

 composition of honey. Experiments with chloroform iu introducing 

 queen bees into hives and in curing the swarming impulse were 

 successful, but the author is not yet prepared to give positive advice 

 regarding the use of this method. Brief notes are also given on experi- 

 ments iu removing queens during the season of storing honey, in 

 feeding back, and on cuckoo bees.

A TREATISE on FLAX CULTURE, O. LuGGER, Ph. D. (pp. 3-31, illus- 

 trated). — A useful summary of information regarding the cultivation 

 of flax for hber and seed as it is carried on in Europe. The author is 

 able to draw largely on his experience in flax culture, gained for the 

 most part in the flax growing region of Westphalia. The article also 

 contains a brief preliminary report to the Governor of the State on 

 experiments in 1890 near Wiudom, Minnesota, by the author, with a 

 view to ascertaining the cause of an obscure disease of tlax in which 

 " the stems of the plant assume a yellow color at the base and a blackish 

 one at the tip, and the leaves — and later the stems — die and disappear." 

 The experiments were of three kinds : (1) with fertilizers on land 

 exhausted by flax, (2) with fungicides applied to seed in infested soil, 

 and (3) with infusions pre[)ared from the chafi' and straw of flax.
