There was bitter disappointment in wren circles earlier in the season when, with the presumption of inexperience, the pump was filled regularly with coarse twigs, which were promptly dislodged at nightfall. Undiscouraged at this defeat, the morning hours were utilized for rebuilding with a persistency well worthy a more intelligent effort; they worked and sang, sang and worked, until a cigar box was nailed to a tree for their special accommodation. This was nearly full of twigs when they decided that the building-site was ineligible, a decision hastened by the fact that just at this opportune time a glass fruit can was left upon the piazza shelf. No sooner was this glass house seen than its possibilities were realized and plans were quickly made for a kind of crystal palace experiment. Under other circumstances this might have been a dangerous precedent, as certain unneighborly conduct toward their little brothers of the air had at various times fairly invited the throwing of stones. The can was half full of tiny fagots, and Jenny was thinking of settling upon the mattress of wood fibre when the thrifty housewife turned them adrift summarily, well aware that this kind of housekeeping, within easy range of neighboring cats, would not be successful. Before such supreme content, who could have the heart to undeceive them? And yet, the can was turned upside down before they could be made to understand the situation. Like Thoreau, they did not wish to practice self-denial unless it was quite necessary! After the failure of this crystal scheme, it was a difficult matter for Jenny to make up her mind as to a further preference, but when she really decided it was with such entire good faith as left no doubt in her lover’s mind as to her judgment. This was more flattering as it was his own choice, their last year’s home thoroughly remodeled, to which he had repeatedly called her attention, vainly. So the hole in the house jet at least answered the question, “Where are the birds in last year’s nests?” for the wrens moved in regularly, the tenor having a perch upon a projecting bracket where Jenny joined him, a regular little termagant, scolding with all her might whenever the kittens looked that way. Marsh wrens, small brown birds, with barred wings and tail, breed in or about the swamps and marshes of Lake Champlain. They are intensely interesting from their habit of constructing several nests but one of which is utilized for housekeeping. After the real nest is made and the first egg laid, the male stays closely at home busying itself with building several nests, which are to all appearances entirely superfluous. In locating these he does not go beyond the immediate neighborhood of the true nest.
