We claim: 1. A bag adapted to be filled in the field and stacked in layers to provide a barrier comprising, a length of material having a plurality of alternating sections, wherein one section is filled with a particulate material and the adjoining section is unfilled, in which there is an unfilled section at both ends of the bag and in which each section to be filled is open with means to seal the opening after it has been filled. 2. The bag of claim 1 in which the stacked layers of bags provide a barrier against the flow of liquids, water, earth, mud, silt, explosive blasts, gunfire or shrapnel. 3. The bag of claim 1 in which the filled sections are filled with sand, earth, concrete, aggregate, or particulate matter. 4. The bag of claim 1 in which each bag has two filled sections and three unfilled sections. 5. The bag of claim 1 in which the material is woven polyethylene, woven polypropylene, burlap, canvas, ballistic nylon or woven organic fibers. 6. The bag of claim 1 in which each filled section has four slanted sides. 7. The bag of claim 6 in which the sides are slanted at an angle of from about 30 degrees to about 40 degrees. 8. A bag adapted to be filled in the field and be stacked in layers to provide a barrier comprising a length of material having alternating sections, each section having four sides, wherein one section is to be filled with a particulate material and the next adjoining section is unfilled, with unfilled sections at both ends of the bag, in which one side of each section to be filled is open with means to seal the open side after it has been filled. 9. The bag of claim 8 in which the stacked layers of bags provide a barrier against the flow of liquids, water, earth, mud, silt, explosive blasts, gunfire or shrapnel. 10. The bag of claim 8 in which each bag has two filled sections and three unfilled sections. 11. The bag of claim 8 in which the material is woven polyethylene, woven polypropylene, burlap, canvas, ballistic nylon or woven organic fibers. 12. The bag of claim 8 in which the means to seal the fillable sections comprises an adhesive on the inner edges of each open side. 13. The bag of claim 12 in which the adhesive has peel-off strip covering the adhesive. 14. A method for forming a sandbag structure in the field comprising, transporting a plurality of sandbags to the field, each sandbag comprising a length of material having alternating sections, wherein one section is open with means to seal the opening and the next adjoining section is unfilled, with unfilled sections at both ends of each sandbag, filling each open section with sand, sealing it and stacking the sandbags in layers. 15. The method of forming a sandbag structure of claim 14 in which each bag has two filled sections and three unfilled sections. 16. The method of forming a sandbag structure of claim 14 in which the material is woven polyethylene, woven polypropylene, burlap, canvas, ballistic nylon or woven organic fibers. 17. The method of forming a sandbag structure of claim 14 in which each filled section has four slanted sides. 18. The method of forming a sandbag structure of claim 17 in which the sides are slanted at an angle of from about thirty to about forty degrees. 19. The method of forming a sandbag structure of claim 14 comprising stacking the sandbags in a parallel direction. 20. The method of forming a sandbag structure of claim 14 comprising stacking the sandbags in both a parallel and a transverse direction.
