SPECIFICATIONS 



PLAN 4 D. 



CABIN FOR - RANSER SHELTER 

 (Region of Deep Snow Pall) 

 12' x 18' - 8" Walls 



This building is designed to fulfill a need for an 

 extra strong small cabin in regions where snow fall is ex- 

 ceedingly heavy as for example - on certain parts of the 

 Plumas, Tahoe and Eldorado, and at perhaps other places 

 within the Sierra Nevadas. The structure as drawn will 

 support any snow load of either roof or side pressure that 

 will ever occur . 



These specifications are intended to embrace all 

 material necessary in the erection and completion of the 

 building in all its parts and to furnish such instructions 

 as appear necessary to give the builder a general idea of 

 the plan. They are written in much detail since where these 

 buildings will be erected expert labor will be scarce; there- 

 fore inexperienced labor will perhaps be used to put up the 

 house in most cases. The general plan as regards construction 

 of frame and other vital parts of the structure is to be 

 followed unless permission to deviate from the plans and 

 specifications has first been secured from the District For- 

 ester. Deviations of minor consequence, however, may be made 

 by the builder to take care of unforeseen local conditions 

 and circumstances. 



EXCAVATION. 



A level site must always be provided. If necessary to 

 excavate sloping ground to provide this, the excavations should 

 be level and smooth and perfectly solid throughout. Never 

 place the structure on loose shifty soil. Where necessary 

 to grade into unlevel ground for the purpose of providing a 

 level building site, the sides of the excavation must clear 

 the building by at least 3 feet and the rear of the excavation 

 must give a clearance of at least 6 feet. Snow on slopes 

 settles with the plane of the hill. The settling action re- 

 presents an enormous force. The wide clearance at the rear 

 is necessary, therefore, to prevent the settling snow from 

 pushing the building off its foundation.
