No. 4.] MARKET GARDENING. 107 



to stay on the cabbage, but want it washed off before the 

 head comes to maturity. We have different ends in view 

 with the two different plants. 



Mr. Boise. Isn't arsenate of lead better for the potato, 

 because it will not burn the top at all ? 



Dr. Fernald. I am a thorough convert to the use of 

 arsenate of lead everywhere it can be used. I regard it as a 

 better and more effectual substance to use, because it stays 

 on the foliage longer, and because there is no danger of 

 burning the foliage. The case of the cabbage is rather an 

 exception, because of the peculiar conditions surrounding it. 

 I would unhesitatingly recommend arsenate of lead in most 

 cases. 



Mr. Smith. I understood the essayist to say he recom- 

 mended the landside plough for preparing a market garden. 

 Wouldn't you recommend the use of the swivel plough? 



Mr. Kinney. I have yet to see a swivel plough that 

 would turn market garden land in good shape. Our land is 

 worked twenty inches deep, and it is worked soft. There 

 may be places where the swivel plough can be used to the 

 best advantage, and I would recommend that every market 

 gardener have a swivel plough. There may be one made that 

 will work well. On all garden land that I know about the 

 land has been turned largely in ridges. In Arlington on very 

 large fields the crops are raised in ridges. In the Connecti- 

 cut valley it is worked differently. I have not yet found a 

 swivel plough that would do satisfactory work for me. The 

 best landside plough I know is the National, whicli is made 

 the same as the sulky. The sulky would do just as good 

 work. Where you plough in ridges, the landside plough is 

 preferable. 



Mr. Smith. We have a swivel plough, but we have not 

 ploughed ten acres with it. We think there is nothing bet- 

 ter than a good chilled plough . 



Mr. Kinney. I do not find many men who know how to 

 plough a big piece with a landside plough. You should be- 

 gin in the centre and plough around the centre. This gives 

 you a furrow turned in from the edge all around. 



^Ir. Smith. How much income do you expect from each 

 sash each season?
