How many librarians does it take to install a fruit cage?

This fruit cage measures 5m x 4.5m. Guess how many librarians it took to install the roof construction? And? Sure about that number? Okay: the answer was 3 plus one non-librarian. It covers all the existing fruit bushes left by the house's previous owner, plus the new plants we brought along: mainly raspberry plants, and we also stored our two, potted blue berry bushes in there. Apart from 2 or 3 times when a little bird found its way into the cage, and needed to be shooed out of the door, the cage has been a success stories. No loss to animals, and this year's harvest of gooseberries, blue berries, as well as white, red and black currants was keeping us very busy. For a couple of weeks in July and August we harvest for 1-2 hours each night (not only in the fruit cage, but also in other parts of our garden). So the cage has really delivered. CHG
