158 THIRD AXXUAL REPORT 



and see that each colony is wintered on such food. Three 

 or four such combs will winter a fair colony safely if con- 

 fined on those combs late in the fall and the hive contracted 

 *o fit the same. 'This is one of the most important conditions 

 for success in wintering. 



2. If in the fall the bees have gathered this unwhole- 

 soine honey from the above-named sources, it should all be ex- 

 tracted and either exchanged for those honey-combs, or feed 

 the bees good honey or sugar syrup imtil winter stores are 

 secured. This should be done before cold weather in the fall. 



3. Hives contracted and made comfortable, whether in 

 cellar or outdoors. 



4. If wintered in cliafif hives outdoors with feed as above 

 directed, and there come one or two warm spells during win- 

 ter so that l)ees can iiave a cleansing flight, they will not 

 have dysentery or dead brood, and will be much stronger 

 •,vhen clover opens. 



If wintered in the cellar the bees will not need as much 

 hcney, and if the winters are generally long with doubtful 

 warm spells, the cellar will be best. Bin to keep the bees 

 from dysentery, so often fatal to cellar-wintered bees, they 

 'hould have such winter stores as above spoken of, then the 

 cellar kept at a uniform temperature, about 42 dcg. F., ven- 

 tilated so the air is fresh, and no mold will form in the 

 cellar. Fresh air-slacked lime on the bottom of the cellar 

 may help if it is damp or has ]ioor air. 



5. Dysentery will not appear if bees are kept on sugar 

 syrup, or best-grade white clover or basswood honey, and arc 

 in a dry place, cither sheltered by cellar or chaff-hive.

FORMALDEHYDE EXPERIMENTS. 



Formaldehyde, by the medical experts, is now considered 

 the best of all disinfcetants ; I have great faith that we may 

 yet learn its use, and save infected foul-broody combs. 



Mr. C. II. W. Weber has conducted some valuable experi- 

 ments. Eai'ly in 1903 I decided to do some experimenting, 

 having insjtected several infected apiaries. We got a carpen- 

 ter with well-seasoned lumber to make some perfectly air- 

 tight boxes to hold brood-frames, two tiers deep, as per the 

 photograph herewith. Mr. Weber's lamp was used in several 

 trials. Where we used a great(>r amount, and longer confined 

 than instructions called for, the combs with all cells unsealed, 

 containing dried scales of foul brood, after fumigating and 

 airing were placed in hives with bees on them. The chemical 

 action was such that the bees at once cleaned them out, and 

 no signs of disease has a])peared in them since. But in those 

 combs having honey or pollen in the infcseted cells, or those 

 capped over with brood underneath, they were so covered that
