The sill can be attached to thispart by using the regulation metal clamps,to which the sill can be bolted. The boltsfor retaining the clamps in place can beput into the foundation concrete while thefoundation concrete is yet soft. Fig. 3 is one of the forms as used formaking the sides. Sometimes the side wall is made accord-ing to the description shown in Fig. 4,. which is a sectional drawing. Another manner of making the walls isshown in Fig. 5. The result of this planof making the foundation posts, walls andfloor, there is an insect-tight foundationobtained. To this rat-proof foundation itis possible to construct the necessary bodyand roof of the storage plant with the re-quired number of doors, windows and ven-tilating shafts. Care should be taken not to get too manypieces of timber in connection with theconcrete, for the reason that if some kindsof lumber is formed as a part of the con-crete wall, this timber may wrap or springout of line and crack the concrete. I sawone very well designed rat-proof cribruined because in the erection of the struc-ture all of the posts for the supporting
