in the soil. In no case could it be attributed to the action of insects, and 

 the fact that 3G per cent, were afPected when covered with sulphur indicates 

 that fungi are not active agents.

The great difference in the number of scabby tubers in the two varieties, 

 the increase of scab where soda hyposulphite was used, and the well-known 

 fact that scab is most common in decaying organic matter, are pointers 

 that will be made use of in investigations during the coming year. 



TOMATOES. 



COMPARATIVE TEST OF VARIETIES. - 



The variety tests of tomatoes was confined to one hundred and twenty- 

 eight sorts, of which twenty-three were new, either as strains or varieties. 

 In most cases twelve plants of a variety were used, and as near as pos- 

 sible were given the same care. They were trained to wires on a trellis, and 

 we were able to gather the fruit w^ithout danger of mixing the varieties or of 

 injuring the vines. 



The weather for several weeks after planting in the field was quite cold 

 and the growth was very slow. During August the severe droiith and 

 cold nights held back the ripening of the fruits, and our first picking was 

 not made until the 26th of August, although one variety showed ripe fruits 

 on the 15th of August. 



The new varieties, and such of the old ones as gave a large yield or pos- 

 sessed other qualities that make them valuable, are included in the follow- 

 ing table which show^s the comparative time of ripening, the size, produc- 

 tiveness, etc., of the different sorts. The column showing the per cent, of 

 germination is taken from the per cent, that vegetated in the seed boxes. 

 The average would have been much higher had we been able to maintain 

 a svifficiently high temperature in our forcing house.
