Colour of the Strir/. A range of colour similar to that of the bines 

 also obtains in the strigs of the hop cones. "Strig" is the name com- 

 monly used to denote the axis of the hop cone ; on the swollen nodes of 

 this axis are inserted the flowers with their accompanying bracts and 

 bracteoles. The nodes of the strig are usually of a darker colour than 

 the internodes. In most of these plants the internodes are reddish with 

 the nodes a dark purplish red. In extreme cases the strig is pale green 

 with usually a faint reddish tinge at the nodes, or the strig is dark red 

 throughout. The colour in individual plants fluctuates to some extent 

 even in the hops of the same year ; certain plants however produce green 

 strigs (green throughout or green with reddish nodes) year after year 

 while others consistently produce red strigs (red internodes and dark red 

 nodes or strig red throughout). 



It was expected that the colour of the strig would be correlated with 

 that of the stem. Of those plants with red bines most had red strigs 

 with dark red nodes, a few had strigs dark red throughout while in some 

 the strigs were green with pale reddish nodes. Only one of the $ plants 

 had green bines ; unfortunately this plant became diseased and had to 

 be destroyed before the hops matured and so the colour of the strig was 

 not determined. Those plants of which the bines were intermediate in 

 colour between the green and the red plants had strigs which were almost 

 invariably recorded as green (or faintly reddish) with reddish nodes. It 

 would appear therefore that there is a tendency for the plants with red 

 bines to produce red strigs and those in which the red colour of the bines 

 is less pronounced to produce green or pale reddish strigs. As is well 

 known the green-bined cultivated varieties of hop have green strigs. 



One plant, Z .58, has strigs which have a polished (vernicose) appear- 

 ance ; this character has appeared, though not so pronounced, in two 

 other plants. 



(8) Degree of susceptibility to the mildeiu Sphaerotheca 

 Hunmli {DC.) Burr. 



Accounts have already been published ((4) to (7)) of the differences 

 shown by individual seedlings as regards susceptibility to the attacks of 

 the Hop Mildew. A resume of the chief facts observed will be given, and
