The day after yourdeparture I went to visit the fir wood, when I had the goodfortune to extract eight males of the Sirex; two of these Ipurposely let go; they proved very strong on the wing, andascended with a loudish hum to an invisible height. Fromthis it appears that the mischief arises from allowing deadtrees to remain standing or lying about; and timber ought tobe well examined before it is employed in building; for I un-derstand that considerable numbers of the males have beentaken flying about the tower of York Minster, no doubt seek-ing the females which were issuing from the timbers that sup-ported the roof, and which would be, of course, greatlyweakened by the constant and continued operations of theLarvae, as well as rendered more combustible by the multi-tude of passages and the quantity of dust which they create. The plant is Lapsana communis (Common Nipplewort). 2dr/.
