— the larva of the Crane Fly or Daddy-long-legs, was found. 

 This greedy little monster, while in my possession, scooped out 

 the contents of two other large bulbs — i.e , the fleshy part of 

 the bulb itself. Thus it had certainly eaten three, and most 

 probably others previous to its capture, before an accident put 

 an end to further depredations. 



Frequently new bulbs may be found that appear to have 

 been formed with great difficulty, probably due to such mis- 

 chief as that caused by this grub to the old bulbs. In spite of 

 so many precautions, therefore, it would seem that the wood 

 garlic has still to fight against subtle enemies. 



It frequently happens that when the bulbs have been buried 

 below the average depth by miniature landslips — so common 

 a feature in woodlands having a stream flowing through them — 

 or with river silt, provision is made to restore the next bulb 

 to the normal level. In these cases the otherwise short piece 

 of axis (just sufficient to hold the various leaves — no more) 

 becomes elongated between the sheathing scale leaf and the

 having this piece of stem (an elongated solid internode) de- 

 veloped, though in this particular example it was formed to 

 carry the new bulb from under a stone by which it had been 

 accidently covered. 



From this sketch it will be seen that its behaviour
