Written at Grasmere. The effect of her laugh is an extravagance; 
      though the effect of the reverberation of voices in some parts of 
      the mountains is very striking. There is, in the "Excursion," an 
      allusion to the bleat of a lamb thus re-echoed, and described 
      without any exaggeration, as I heard it, on the side of Stickle 
      Tarn, from the precipice that stretches on to Langdale Pikes.

In Cumberland and Westmoreland are several Inscriptions, upon 
     the native rock, which, from the wasting of time, and the rudeness 
     of the workmanship, have been mistaken for Runic. They are without 
     doubt Roman.

       The Rotha, mentioned in this poem, is the River which, flowing 
     through the lakes of Grasmere and Rydale, falls into Wynandermere. 
     On Helm-crag, that impressive single mountain at the head of the 
     Vale of Grasmere, is a rock which from most points of view bears a 
     striking resemblance to an old Woman cowering. Close by this rock 
     is one of those fissures or caverns, which in the language of the 
     country are called dungeons. Most of the mountains here mentioned 
     immediately surround the Vale of Grasmere; of the others, some are 
     at a considerable distance, but they belong to the same cluster.
