And now to consider briefly the economic values of some of the 

 more popular and useful vegetables. These calculations have been 

 made from this year's crops with the exception of the parsnip results, 

 which are from last season. I would like at this point to express my 

 great indebtedness to my co-worker, Mr. Geo. Baldwin, F.R.H.S., 

 without whose assistance these records would not have been obtained. 



The method adopted was to weigh the seed necessary to plant 

 a fixed area of ground, and to add to the cost of the latter the expenses 

 involved in labour and manures, then to observe the period the crops 

 occupied the ground, and eventually to weigh the harvested crop. 



In the case of potatos two varieties were tested, viz. ' Windsor 

 Castle ' and ' Gordon Castle.' Seven rods were planted in each case 

 with 56 lb. of " seed." The detailed cost of the crops were, with 

 ' Windsor Castle ' : 



Cost of seed ...... 14 o 



Farm manure, 1 ton . . . . 10 o 



Prentice's manure,' 14 lb. 26 

 Cost of labour for — 



Digging 14 o 



Hoeing ...... 50 



Earthing ..... 50 



Harvesting ..... 76 



Spraying (twice) . . . . 12 6

The weight of the crop was 11 cwt., i.e. 176 lb. to the rod. 



In the case of ' Gordon Castle,' the cost of seed was 21s., the other 

 expenses being the same. The yield was 17 cwt., i.e. 272 lb. to the 

 rod. Therefore the cost per rod of ' Windsor Castle ' was 10s. for 

 176 lb. and of ' Gordon Castle ' us. for 272 lb. 



The time the ground was occupied in both instances was twenty- 

 one weeks. 



Dried Dwarf Beans. — Two varieties were grown, ' Dutch Brown,' 

 and ' Everbearing Dwarf White.' One rod of ground was allotted 

 to each. The costs of the crops and results are given below.
