In a letter by Philip Allsopp in our Sunday paper captioned “If the pattern of erosion is studied it is possible to predict where it will occur and plan maintenance accordingly” the following passage occurs:
“It is wrong to state that the cycle of erosion is now starting – it has been going on as long as the Amazon discharged mud into the Atlantic, and it is wrong to state that the cycle is 40 years – it is closer to 38 years”.
The last figure should be 33 years not 38 years. We regret the error.
