Ayton and Helmsley, on the 4th at Mickley, on the 7th at 

 Cowesby, on the 17th at Lythe and on the i8th on the Hamble- 

 ton plateau near Cold Kirby. 



The first Harvest crop was cut on August 12th at Raskelf and 

 Thirsk, on the 13th at Catterick Bridge near Richmond, on the 

 1 6th at Camphill, on the 20th at Mickley and Husthwaite, on 

 the 23rd at Great Ayton and Helmsley, on the 30th at 

 Cowesby, on the ist of September at Lythe and on the 2nd on 

 the Hambleton plateau near Cold Kirby. This will give us as 

 the average of the nine principal localities behind Thirsk in 

 round numbers.

So much depends upon difference of soil and exposition, and 

 in the case of the cultivated crops upon the time of sowing the 

 seed, the sort of seed, the state of the cultivation of the land and 

 the state of the weather at the time the crops have to be secured, 

 that results obtained in this way can only be taken as broad 

 approximations. Nevertheless it would seem likely that none 

 of the figures given above are far from being a correct representa- 

 tion of the postponement of the time as compared with Thirsk 

 when the hay crop and harvest are ready in an ordinary season. 

 The part of our field of study where they are ready first seems 

 to be what we may call the Veronica triphyllos tract, a surface 

 of light sandy ground which is situated on the Acomb side of 

 York and has something of a southern slope. Between York 

 and Thirsk the average difference is not material ; the gardeners 

 say that at Thirsk vegetation is somewhat more liable to be 



July 1888.
