Tynehead, Borthwick, Fushie Bridge, Gorebridge. 
Saturday, 19th May 1855. 
Party of 100 met at the North British Railway Station at 
10.45 a.m. and proceeded to Tynehead, thence walked to Borth- 
wick and Fushie Bridge, and returned by train passing Gorebridge 
at 4.57 p.m. Return third-class tickets, 1s. 2d. 
Vegetation very far back, three weeks or a month behind. 
Observed colours in vegetation as they affected the eye, found 
that the yellow dandelion and green grass were very marked 
features. M‘Cosh talks of the red stalk of the dandelion, but in 
most cases they were green, and even when a reddish or brownish 
tinge was present it did not appear to the eye. The marked 
effect was produced by yellow and green, and these, although 
not complementary colours, were pleasing. So also in many 
places nothing seen but the yellow primroses and the green 
sward—without any other colour, no white nor red. Some of 
the party visited Arniston also.
