in the hands of its captor, presumably for purposes of identifica- 

 tion ! Amongst the birds the peregrine was perhaps the most 

 noteworthy, and the landlord at the Cleveland Arms convinced 

 the party that fine trout occurred in the adjoining river.

 reports that as the district to be investigated was practically 

 an unworked one, the season opportune and the weather in- 

 dications favourable, he and Mr. Winter anticipated a successful 

 issue to their quest for spiders. Their hopes, however, were 

 not fully realised, for, with one exception, these creatures were 

 not at all plentiful, either as individuals or species. This 

 scarcity was most noticeable along the higher reaches of the 

 river, where the prevailing humidity of the climate in conjunction 

 with the underlying impervious strata produces extensive 

 tracts of water-logged ground apparently as inimicable to 

 spiders as it is favourable to some other forms of both animal 

 and vegetable life. For the first two da^'s the prescribed 

 routes were adhered to. Good use was made of the brief
