bone always contained a slightly higher per cent of phosphoric 
acid. The eggs were both brown and white shell, thirty-two eggs 
being used from Pen 1 in which oyster shells were fed, and forty- 
one eggs from Pen 2 which had ground bone. More eggs were 
laid by those fowls which had ground bone. The average of the

During the year a new poultry-house has been built, similar to 
the smaller one built the year before, with pens arranged conve- 
-niently for feeding experiments. The building is forty-two feet 
long east and west by eighteen feet north and south; six feet high 
on the north side, five feet high on the south, and ten feet at the 
peak. The four pens, each twelve feet by ten and one half feet, 
are on the south side, and dust bins take two feet from the north 
side, leaving a passage-way four feet wide. From this passage, 
wire-net doors, six and one-half feet by two and one-half, open 
into the pens, and a lath door, four feet wide and two feet high, 
hinged at the top, swings under the roost platform far enough to 
allow food to be placed in the shallow food trough on the floor, 
which is four feet long, six inches wide and two inches deep. 
Separating the pens, are lath partitions, and on three sides of the 
roosting place, from the floor of the nests, which are below the 
platform, are tight partitions reaching to the tight ceiling above. 
Just above the dust bins, on the north side, are feed boxes of three 
compartments each. Two ventilating shafts, three by twelve inches 
inside, extend through the roof to within six inches of the floor. 
_ There are four windows on the south side, one in each pen, four 
feet wide by three feet high, one foot from the floor. <A box two 
feet by four feet and six inches deep, containing a dust bath, is on 
the floor of each pen. The roof is covered with roofing paper, a 
thickness of “rope-roofing”’ over a coating of cheaper paper, and
