How should this be correctly transcribed?

How do you think the following place/street name entry should be recorded?

It comes from the 1881 census from the Rickmansworth area.

I would be interested to see if people agree - so make a note of what you think it is and record it as a comment after reading on - so I can compare the different ways people read it.

Where in Hertfordshire is it - Barnville Wood?

Harpenden

Jacky's question was, perhaps, easier than some as errors such as "rn" and "m" being confused can occur in print as well as in handwriting - and once you have discovered Bamville Wood is near Harpenden it is easy to locate the farm where Alfred Thomas White was living in 1911. 

If you are trying to find where your ancestor lived you may find the approach I used in Bamville Wood, Harpenden, 1911, or the more detailed Locating Census Addresses on Maps, helpful.
