I was very happy when I got this book. The best part is absolutely the visual explanation on how to manage top bar comb through many illustartions. All the combs are marked with numbers for easy explanation, one clearly see where which comb goes if doing a:
spring hive management, honey flow management, strong honey flow, combining hives, hive removal, brood nest maintenance, Queen-cell building hive, two Queen system, making a divide/split, etc ...
It does it for me since I am avery particular person and like to know exactly how things work. Les Crowder did great job with this book since I feel very comfortable to use his teaching next season. They are very clear.
Highly recommended book!
