t During tlic latter part of the day, that appearance was discoverable in 

 the clouds which gives them the appearance of being charged with the

X People, in cleaning ditches which lie parallel and near to hedgerows of 

 trees, are very apt to cut some of their roots ; a circumstance wliich seems
