it not that the greater warmth to some extent counter- 

 balances the higher rainfall. 



In Saaz and Schwetzingen red hops are grown, whereas 

 Dauba and Eottenburg for the most part produce green 

 hops. 



A glance at Table A will show that here the climate is 

 harsher than in the habitat of the red hop. The mean 

 summer temperature is 13-5° C. at Dauba, and 14° at 

 Eottenburg ; both places are at a higher altitude, and the 

 months of April and May are appreciably colder than in the red 

 hop districts. At Eottenburg the summer rainfall is greater 

 by 52'6 mm. than at Dauba, but is apparently compensated 

 by greater warmth than in the latter district. In any case the 

 climatic conditions at both places are less suitable for red hops 

 than those prevailing at Saaz and Schwetzingen ; otherwise 

 it would not be clear why green hops should be grown at 

 Dauba and Eottenburg, seeing that the red varieties are 

 more sought after. 



In New York State, notwithstanding the warmer climate, 

 the hops are of lower quality owing to the unusually 

 heavy rainfall in May and June, i.e., the spring is generally 

 very wet, in consequence of which the quality of the cones, 

 as is well known, is unfavourably influenced. A wet 

 spring in European districts commonly results in plenty of 

 foliage, but the production of barren cones and poverty in 

 lupulin. 



In Oregon the climatic conditions are highly favourable 

 to hop-growing, the mean summer temperature, 14'9° C, 

 closely approximating to that of European red hop districts. 

 Nevertheless, the high rainfall renders the production of fine 

 hops an impossibility. 



Of course, in view of the paucity of available data, the 

 foregoing considerations on thei climatic conditions of the 

 hop plant possess only a limited value, the more so because
